With this year's JLT Community Series now done and dusted, attention turns to round one and the start of the 2017 AFL season. Who is set to be the most impactful player at your club? Which player is set for a breakout year? And who can you expect a solid rebound year from?

ESPN.com.au's AFL draft expert Christopher Doerre - aka Knightmare - has the answers.

Adelaide:

Most impactful draftee: There aren't too many first year draftees certain to receive early season opportunities for Adelaide. However, Jordan Gallucci, with his versatility to play multiple positions way get a look in. The first round selection will look to string together some strong form in the SANFL early in the year.

Breakout contender: Missing the first half of 2016 with a stress reaction in his foot, Curtly Hampton returned to the SANFL to play the second half of last season. Hampton has performed consistently throughout the preseason averaging 20 disposals and looks set to establish himself in Adelaide's best 22 as a running midfielder.

Rebound season: Andy Otten, who last played at AFL level in 2014, has had a horrible run of injuries and was unable to break into the senior team in 2016. Otten has enjoyed a full preseason and through his three games has averaged 18 disposals and five marks. He appears to be a strong chance to re-establish himself in Adelaide's best 22.

Brisbane:

Most impactful draftee: Brisbane's hunt for some polish through the midfield is likely to come through Hugh McCluggage. It's clear there will be an adjustment period to the pace of AFL play for McCluggage, who laid just one tackle in his two preseason games, but he's certainly one of the top 2016 draftees to look out for.

Breakout contender: In three years Jake Barrett was unable to break into GWS' midfield, but after being delisted and taken by Brisbane with their second rookie selection, he will be eager to make the most of his second chance. He will need to be promoted to Brisbane's senior list, but certainly looks to be a best 22 player.

Rebound season: He played just two senior games in 2016, but Brisbane's new captain Dayne Beams will add substantial value through the midfield. Beams can get back to his 26+ disposal, one goal a game average and once again re-establish himself as one of the competition's best midfielders.

Carlton:

Most impactful draftee: Carlton's most promising youngster has been Zac Fisher who looks most likely to break through for regular senior games in 2017. His 19-disposal average from 10 WAFL League games in 2016 suggests that the ball winning midfielder can contribute significantly through the midfield.

Breakout contender: Caleb Marchbank missed much of the 2016 season with ankle and shoulder injuries, but has put his best foot forward this preseason since crossing from GWS. Marchbank, who averaged 19 disposals and seven marks in preseason, is a player the Blues can build around long term.

Rebound season: He played 12 senior games in 2016 for GWS before finding himself pushed out and at the Blues. Rhys Palmer was proved to be a prolific ball winner in the NEAFL -- one match racking up 52 disposals, 14 clearances and 11 inside 50s. Since joining Carlton, Palmer has spent more time through the midfield which should see his output increase this season.

Collingwood:

Most impactful draftee: Father-son selection, Callum Brown is likely to receive senior AFL opportunities when he has recovered from glandular fever. Due to stiff midfield competition Brown is most likely to receive opportunities as a forward who pushes through the midfield and could possibly become a regular of the 22 by season's end.

Breakout contender: Tom Phillips appears set for round one selection on the back of three strong preseason performances. Phillips has averaged 21 disposals, seven marks and one goal and has impressed with his clean ball use and work rate. Phillips is another Magpie that could establish himself in the club's best 22.

Rebound season: With only nine career games in his first four seasons, Jackson Ramsay appears to have recovered from last season's ruptured ACL. He averaged 28 disposals and nine marks in Collingwood's third preseason match and if healthy is sure to earn a position in Collingwood's best outfit.

Essendon:

Most impactful draftee: The 2016 number one overall draft choice, Andrew McGrath has had some great moments through the preseason without looking like an established best 22 player. However, over the course of the season expect improvement and for McGrath to provide run-and-carry off the half-back flank.

Breakout contender: With 10 Bombers returning after the 12-month doping ban, and many of those players returning to prominent roles in 2017, it is more likely that several of the young players improve incrementally rather than break out.

Rebound season: Looking rejuvenated after the one-year ban, Jobe Watson will be hungry to make an impact when he returns to the field in 2017. Watson averaged 23 disposals across Essendon's three preseason matches.

Fremantle:

Most impactful draftee: He was unable to take part in preseason due to offseason shoulder surgery, but Luke Ryan, as a mature age defender, looks to be a real shining light for the Dockers. Ryan is a clean ball user that should quickly become part of his side's best 22.

Breakout contender: After playing just 13 matches in 2017, Ed Langdon has taken further steps towards establishing himself into Fremantle's best side. Through his three preseason matches, he averaged 15 disposals and one goal.

Rebound season: Aaron Sandilands, who played just five matches in 2016 due to a collapsed lung and broken ribs, appears one of the sure beneficiaries of the new, no third-man-up at ruck contest rules. In both of his preseason games he led the way in hitouts, while against Collingwood also contributed 15 disposals, four marks and a goal.

Geelong:

Most impactful draftee: Most ready to contribute at AFL level is mature age defender Tom Stewart. He has averaged 14 disposals and six marks through his three preseason matches and as a versatile player appears to be in Geelong's best side.

Breakout contender: Traded from Carlton to fill the considerable hole left by the retirement of Corey Enright, Zach Tuohy has been outstanding, averaging 28 disposals as Geelong's primary rebounder from the back half.

Rebound season: Returning from injury, Jackson Thurlow has averaged 18 disposals from his three preseason matches and looks ready to claim a position down back.

Gold Coast:

Most impactful draftee: Jack Bowes, off the back of a strong preseason campaign, looks likely to receive early opportunities. Bowes contributed 11 disposals in each of his two matches with his skills and versatility to play midfield on display.

Breakout contender: With greater midfield responsibility from round 16 onward, Touk Miller made the most of this opportunity by averaging 28 disposals, 12 contested possessions and six tackles. While the Gold Coast midfield is looking much deeper this season, preseason signs suggest that Miller will start the season playing more minutes through the midfield.

Rebound season: He has become somewhat of a forgotten man, but Michael Barlow, who joined as a delisted free agent from Fremantle last season, could be a great pick-up for the Suns. This preseason Barlow has averaged 26 disposals and four tackles and is certain to walk straight into the side's midfield.

GWS:

Most impactful draftee: Tim Taranto has been outstanding through his three preseason matches averaging 17 disposals and 5 tackles. On form he should be in the mix for round one selection as a midfielder who is just as capable when pushed forward.

Breakout contenders: As midfielders, Jacob Hopper and Matthew Kennedy are both ready to break out and become more prominent parts of GWS' plans. The question is can Leon Cameron squeeze them both into the senior side as part of the midfield rotation.

Rebound season: Brett Deledio, who moved from Richmond in the offseason as a free agent, will miss the beginning of the season with a calf complaint. The hope will be, when healthy, that Deledio will be the final piece to GWS' premiership puzzle.

Hawthorn:

Most impactful draftee: With Hawthorn entering the 2016 draft with pick 74 and retaining much of their still strong and deep list, it appears unlikely that Hawthorn will breed any first-year draftees this season.

Breakout contender: Second year midfielder and forward, Kade Stewart has made a push to establish himself as a best 22 player, averaging 14 disposals, six tackles and two goals across three preseason matches.

Rebound season: Jarryd Roughead and Jaeger O'Meara will both be expected to have strong rebound seasons. Roughead missed the entire 2016 season with a melanoma, but has been exceptional in preseason where he's spent the majority of his time in the midfield working on his stoppages. O'Meara, previously at Gold Coast, has missed the past two seasons with knee injuries. Since crossing to Hawthorn, O'Meara has stepped things up with each game and looks set to play heavy midfield minutes.

Melbourne:

Most impactful draftee: With Melbourne possessing a deep playing list and coming into last year's draft at pick 46, it is not expected at this stage that Melbourne will breed any first-year draftees this season.

Breakout contender: Veteran ruckman, Jake Spencer, who has never played more than eight AFL games in a season, has been a preseason surprise packet. Spencer has performed strongly through the ruck and in his third and final preseason match kicked three goals which may be enough to earn him round one selection.

Rebound season: Despite Jake Melksham sitting out the past 12 months, he is playing career-best football averaging 19 disposals and six marks. Yet another option for the Demons.

North Melbourne:

Most impactful draftee: Jy Simpkin, North Melbourne's first round selection, appears most likely to receive opportunities in 2017. Simpkin missed most of his draft year with a broken leg, but has shown flashes of talent this preseason with his pace and class.

Breakout contender: As a ruckman, Braydon Preuss already looks to be ready for AFL level. Expect Preuss to be used primarily as North Melbourne's first in line depth ruckman, though he may receive opportunities as the relieving ruckman if he keeps hitting the scoreboard and taking marks forward of centre.

Rebound season: Playing just the nine games in 2016, Shaun Higgins has been impressive in each of his three preseason matches. Going off preseason form, he looks capable of replicating the quality he displayed in 2015.

Port Adelaide:

Most impactful draftee: Mature age key forward, Brett Eddy kicked five goals and four behinds in his final preseason match. Eddy will need to be elevated from the rookie list, and that looks likely to be done in time for round one.

Breakout contender: Likely to break through for early games is Dan Houston who has averaged 14 disposals across half back, looking a natural fit for Port Adelaide.

Rebound season: After missing the 2016 season due to the ASADA verdict, Paddy Ryder looked like his former self, shouldering the whole ruck responsibility with 35 hitouts, 12 disposals, seven marks, three tackles and one goal in Port Adelaide's final preseason game against Hawthorn. Expect Ryder to continue to improve as he shoulders a heavier load through the ruck and plays more games.

Richmond:

Most impactful draftee: He may have missed all three preseason matches, but Shai Bolton demonstrated his flare and offensive prowess in a VFL practice match against Footscray. He has the talent to appear at some point this season up forward when he strings a series of strong performances together.

Breakout contender: Since crossing from Sydney in the offseason, Toby Nankervis has made it clear that he is Richmond's number one ruckman. His tackling, involvement around the ground, contested marking and scoreboard impact have all been selling points that will see him selected for round one.

Rebound season: During his final two seasons with the Suns, Dion Prestia played only 22 games after battling a number of knee injuries. This season, at the Tigers, Prestia will be looking to put a full season together and get back to his best through the midfield.

St Kilda:

Most impactful draftee: Of this year's draftees, Ben Long is St Kilda's most likely to break through for senior games later in the season either as a forward or defender.

Breakout contender: If Jack Steele continues to play predominantly though the midfield, he may become St Kilda's most productive player by season's end. As a midfielder, Steele has the potential to turn in multiple 30+ disposal, 10+ tackle games as well as hitting the scoreboard frequently. A fantastic pick-up for the Saints.

Rebound season: Since being dropped to the VFL last season, Jack Billings looks a completely different player. In his final two preseason matches, Billings contributed 30 and 25 disposals and looks set to return to the senior side as a predominant outside midfielder.

Sydney:

Most impactful draftee: Darcy Cameron has held his own in preseason against his far more experienced opponents, but will face stiff competition for a place as Sydney's relieving ruckman. Has also contributed a goal in each of his three matches and proven to be a serious marking threat in the forward half.

Breakout contender: Whether it's been through attacking the ball aggressively, using it cleanly or injecting pace into the midfield, Zak Jones has provided Sydney with a fresh dynamic through the midfield. Jones has made meaningful strides this preseason with 26 disposals and six tackles against St Kilda and 21 disposals and 11 tackles against North Melbourne.

Rebound season: Sam Reid, who missed a heap of football in 2016 due to multiple injuries, has manged to get through all three preseason matches unscathed. He showed glimpses of his best in the final match taking nine marks.

West Coast:

Most impactful draftee: In the second half of the season, once he has overcome hamstring surgery, Willie Rioli may be a chance to debut.

Breakout contender: Dom Sheed, who played just six senior games in 2016, looks like he will become a regular this season through the midfield after averaging 22 disposals through West Coast's three preseason matches.

Rebound season: Former Swan Lewis Jetta looks much fitter this preseason and demonstrated an improved work rate during his three preseason games. Expect Jetta to finally solidify his position in West Coast's best 22.

Western Bulldogs:

Most impactful draftee: With no dominant rucks, Tim English at some point may enter the mix for selection. He has been clearly outpointed in the contest through the preseason, but what he does do is find the ball around the ground and use it well which will endear him to coach Luke Beveridge quickly.

Breakout contender: Toby McLean has found another gear in preseason, impressing with an average of 19 disposals in his three matches.

Rebound season: Western Bulldogs skipper Robert Murphy, who was forced through injury to sit out the side's remarkable run to the premiership, will be motivated but at 34 cannot be expected to play to the same high standard.
