Watch Now: Fantasy Football Mock Draft: Rookie RBs ( 1:44 )

Even with the start of the 2018 NFL season just around the corner, Fantasy Football players are still participating in last-minute drafts. The advantage of waiting until the last second is that you'll have the latest depth chart moves and injury updates. You can also get your hands on the very latest 2018 Fantasy Football rankings. Those will help you identify the biggest 2018 Fantasy Football sleepers to target, breakouts about to explode, and busts to avoid. For example, finding a player like Davante Adams can make all the difference. He barely cracked the top 20 in most experts' Fantasy football rankings last season, but he became the go-to target for quarterbacks Aaron Rodgers and Brett Hundley on his way to 74 catches and 10 touchdowns. Fantasy players who picked him around the fourth round had a massive advantage last season.

The team at SportsLine was all over Adams from the start, labeling him a WR1 even with Jordy Nelson and Randall Cobb vying for targets, and he finished as the 11th-best wideout. Anyone who listened to their advice made a run at their league title. Now, SportsLine has simulated the entire season 10,000 times and released its latest 2018 Fantasy Football rankings, along with plenty of sleepers, breakouts, and busts.

SportsLine's model is powered by the same people who powered projections for all three major Fantasy companies. And that same group is sharing its 2018 Fantasy Football cheat sheets.

SportsLine's cheat sheets and rankings, available for leagues on many major sites, are updated multiple times every day. Any time an injury occurs or there's a change on a depth chart, the team at SportsLine updates its cheat sheets. When Derrius Guice and Jerick McKinnon tore their ACLs, SportsLine immediately updated its Fantasy Football rankings 2018.

We can tell you SportsLine's 2018 Fantasy Football rankings and cheat sheets are all over Redskins QB Alex Smith. Drafters are sleeping on him all the way until the 12th round.

Smith is coming off an outstanding 2017 campaign that saw him finish as the No. 4 quarterback in standard leagues. He finished the season with 4,042 passing yards, 26 touchdowns and just five interceptions. Smith has also proven to be extremely dangerous with his legs. In fact, over the past three seasons, he ranks fourth in rushing attempts among quarterbacks (192). SportsLine's 2018 Fantasy Football rankings have Smith slotted similarly to quarterbacks like Ben Roethlisberger (seventh-round ADP), Carson Wentz (eighth) and Kirk Cousins (eighth).

Another sleeper that SportsLine's Fantasy Football rankings 2018 have identified: Colts RB Jordan Wilkins.

Wilkins is in line to see the majority of the work the Colts' backfield in Week 1 with Marlon Mack still questionable with a hamstring injury. Wilkins averaged 6.5 yards per carry and 9.3 yards per catch with 10 total scores in 12 games at Ole Miss last season. He's a downhill runner with good hands out of the backfield that will serve as a safety blanket for Andrew Luck, who's playing in his first regular season game since 2016.

SportsLine's 2018 Fantasy Football rankings have Wilkins (15th-round ADP) giving drafters similar production as running backs like James White (11th-round ADP), Adrian Peterson (11th) and Sony Michel (10th).

SportsLine is also high on a wide receiver who's not even on your radar, but has had 13 touchdowns the last two seasons. You can get him dirt cheap in drafts and SportsLine says he'll out-perform players like Michael Crabtree (eight TDs last season), Alshon Jeffery (nine), and Jordy Nelson (20 TDs last two seasons).
