Nick Saban asks, and we deliver. These teams are obviously doing something right to land in the top 25, but it's all about what they will do going forward. We're looking to go 1-0 every week, men. What could prevent these teams from reaching their goals this season?

Here's a look at the biggest question mark facing each Top 25 team.

MVP? How about Heisman Trophy favorite? Tua Tagovailoa has been magic ever since he set foot on the field during the national champion game. He came out on fire to start the season, first winning the starting job and then throwing a perfect 14 touchdowns and no interceptions, despite not attempting a single pass in the fourth quarter. On a 0-100 scale, his FBS-best QBR checks in at 97.8. -- Alex Scarborough

No, not that D'Andre. Walker not Swift. And that's no knock on the running back Swift, either, who has played well so far this season. It's just that Walker, a senior outside linebacker, has been an undeniable different maker. He's off to a phenomenal to start the young season, leading the team in sacks (4), tackles for loss (5) and QB hurries (8). -- Scarborough

Haskins has been a big part of Ohio State's offensive success through the first five games of the season, and a large reason why the Buckeyes have defeated two top-25 teams in TCU and Penn State. He has been named Big Ten offensive player of the week three of the five weeks he has played and has racked up 1,464 yards passing. Haskins is second among all FBS quarterbacks with 19 touchdown passes and only has two interceptions in his first season as a starter. -- Tom VanHaaren

While all the attention was on the dominant defensive front and the dramatic QB battle, the real foundation of Clemson's 5-0 start has been built on the legs of running back Travis Etienne. For the year, he's run for 594 yards and eight touchdowns, and he's averaging 8.14 yards per rush, tops by any Power 5 back with at least 40 carries. But nothing illustrated Etienne's value better than his 203-yard, three-touchdown performance against Syracuse, when he almost singlehandedly carried the Tigers to a season-saving win. -- David M. Hale

No. 5 LSU: S Grant Delpit

It's easy to say Joe Burrow, who has been serviceable at the all-important QB spot, but nobody has played better for the Tigers than safety Grant Delpit. His combination of speed, range and instincts has made him a consistent playmaker. Despite playing in the secondary, he leads the Tigers in tackles for loss (6.5), is tied for the lead in sacks (three), has two interceptions, three pass breakups and five passes defended. -- Sam Khan Jr.

No. 6 Notre Dame: QB Ian Book

The Irish offense is a different unit with Book on the field -- that much has been made clear since he took over the starting job two weeks ago and led Notre Dame to a pair of high-scoring victories. The junior is completing 74.3 percent of his passes and has thrown for seven touchdowns without an interception. His presence makes the Irish a legitimate College Football Playoff contender, which is enough to make him the team's most valuable asset despite limited playing time to start the year. -- Dan Murphy

No. 7 Oklahoma: QB Kyler Murray

Quarterback Kyler Murray has been so good through the first month of the season, he's played himself into every Heisman conversation. Murray trails only Alabama's Tua Tagovailoa in QBR, and has already broken OU's single-game passing efficiency record. His only real weakness this year has been setting alarm clocks. -- Jake Trotter

No. 8 Auburn: LB Deshaun Davis

While Jarrett Stidham and the Tigers' offense continues to struggle, linebacker Deshaun Davis continues to make a name for himself as the anchor of the defense. His arms were just a hair short of knocking down a pivotal touchdown pass against LSU, but the second-year starter nonetheless leads the team in total tackles (43) and tackles for loss (7). He also has a sack and three quarterback hurries. -- Scarborough

No. 9 West Virginia: QB Will Grier

Grier has lived up to the preseason hype, propelling West Virginia to the cusp of the CFP conversation. Grier is second nationally with 371.8 passing yards per game and third in QBR. He also has 17 touchdowns with only three picks. -- Trotter

No. 10 Washington: LB Ben Burr-Kirven

Even for a casual observer, it would be nearly impossible not to notice linebacker Ben Burr-Kirven. The Huskies' defense is among the best units in the nation and Burr-Kirven is one of the major reasons for that. His 59 tackles are nearly twice the amount of the team's second-leading tackler and his 20-tackle performance against Arizona State was the most for a Washington player in over 20 years. -- Kyle Bonagura

No. 11 Penn State: QB Trace McSorley

McSorley's performance against Ohio State made it even more evident how valuable he is to this entire team. The talented quarterback accounted for 461 of Penn State's 492 yards against the Buckeyes and put the offense on his back when needed. McSorley has 1,049 passing yards and 10 touchdowns through the air to go along with 410 rushing yards and six touchdowns on the ground. His leadership, talent and pure play making ability has brought a tremendous presence to this team. -- VanHaaren

No. 12 UCF: QB McKenzie Milton

It is hard to go with anyone other than quarterback McKenzie Milton, who has been efficient and productive through the first month. Milton has thrown for 1,223 yards and 13 touchdowns to only two interceptions, while rushing for 198 yards and five scores. He also ranks No. 3 in the nation in points responsible for, No. 4 in total offense and in the Top 10 in total QBR. He has made a seamless adjustment to new coach Josh Heupel and the slightly varied offensive scheme he has brought to the Knights. -- Andrea Adelson

No. 13 Kentucky: RB Benny Snell

There's no doubt who has been the most valuable wildcat: running back Benny Snell. He leads the SEC with 128 rushing yards per game and eight touchdowns and is the main main in Kentucky's SEC-best rushing attack (259.2 yards per game). He accounts for 33 percent of the Wildcats' yards from scrimmage, which is the most among SEC players. -- Khan Jr.

No. 14 Stanford: WR JJ Arcega-Whiteside

With respect to Bryce Love, who remains Stanford's most talented and most dangerous offensive player, through five games this season it's receiver JJ Arcega-Whiteside who has been the more productive player. Arcega-Whiteside's ability to win jump balls is uncanny -- in the end zone, he plays like power forward getting a rebound. He's responsible for eight of the Cardinal's 11 touchdown receptions and - thanks, in part, to opposing defenses focusing on stopping Love -- has helped make this one of Stanford's best passing teams in years. -- Bonagura

No. 15 Michigan: DE Chase Winovich

No one has been more consistently productive for the Wolverines in September than Winovich. Defense has been an anchor for Michigan in its competitive games so far this year, and Winovich has been at the forefront of that group. His 10.5 tackles for loss are tied for best in the nation, and his 32 total tackles are the second most on the Michigan roster. When the Wolverines have needed a big stop, he's the been one providing it through the first five weeks of the year. -- Murphy

No. 16 Wisconsin: RB Jonathan Taylor

This very well could be wide receiver A.J. Taylor for how he has stepped in and consistently performed in the passing game or safety D'Cota Dixon on defense, but Taylor is No. 5 in rushing yards for all FBS running backs. Part of the reason he's No. 5 is because quite a few other teams have already played five games and the Badgers have played four. Taylor ranks No. 1 in yards per game with 157He has 628 yards and five touchdowns through four games and has been a huge part of Wisconsin's 3-1 start to the season. -- VanHaaren

No. 17 Miami: DT Gerald Willis III

The coaching staff came into the season with high expectations for defensive tackle Gerald Willis, who had underachieved after transferring in from Florida a few years ago. Willis has been dominant inside so far, leading the ACC with 10.5 tackles for loss and helping the Hurricanes defensive front set an aggressive tone. Miami leads the nation with 60 tackles for loss. Willis himself ranks third on the team with 23 total tackles and has fit right into the starting lineup. -- Adelson

No. 18 Oregon: QB Justin Herbert

Not only is Justin Herbert clearly the Ducks' best player, but he's making a strong case to be the No. 1 overall pick in the upcoming NFL draft. Through five games, he's thrown for 1,411 yards with 15 touchdown passes and has shown, at times, to be an effective scrambler. Had the Ducks not collapsed against Stanford, Oregon would be sitting at 5-0 and Herbert would be a much bigger part of the Heisman Trophy discussion. -- Bonagura

No. 19 Texas: LB Gary Johnson

With linebacker Gary Johnson leading the way, Texas ranks second in the Big 12 in run defense, allowing 115 yards per game. The Longhorns also haven't allowed an opposing player to run for 100 yards in a game this season. Johnson also has six tackles for loss and a forced fumble. -- Trotter

No. 20 Michigan State: WR Cody White

Because it wouldn't be fair to credit a single player with the dominant run defense the Spartans played in September, we turn to the most important piece of the puzzle on the other side of the ball. Michigan State's offense has been doing its damage through the air, and White(20 receptions, 300 yards) has been the team's best receiver. A broken hand will keep him out for several weeks, which means others from a talented group of pass-catchers will have to pick up his slack. -- Murphy

No. 21 Colorado: WR Laviska Shenault

Few people in the country were familiar with Laviska Shenault before the season. On a team with several veteran receivers a year ago, he wasn't really needed and finished the season with just seven catches. Through four games, he's been held below 10 catches in a game just once, has caught a touchdown in every game and is very much a candidate to win the Biletnikoff Award as the nation's best receiver. -- Bonagura

No. 22 Florida: DL Jachai Polite

The Gators have put together some strong defensive performances in the early going, and Jachai Polite has been a major contributor. Polite is tied for the national lead with three forced fumbles (Florida is tied for the national lead with 14 takeaways), and leads the team with four sacks. He and Jabari Zuniga are one of just two SEC duos with 3.5 sacks each so far this season, and have combined for 11.5 tackles for loss. Freddie Swain has played well on offense and special teams, too (he ranks No. 6 in the nation in punt return average). -- Adelson

No. 23 NC State: QB Ryan Finley

The Wolfpack knew when the season opened they'd be relying heavily on Ryan Finley, but the senior QB has surpassed all reasonable expectations. Finley has been responsible for 71 percent of NC State's offense so far, completing 69 percent of his throws for 1,313 yards, eight touchdowns and one pick. His 328 passing yards per game ranks sixth nationally. -- Hale

No. 24 Virginia Tech: DB Reggie Floyd

It's been an uneven season for the Hokies, which was probably to be expected considering the number of new faces and moving parts on the roster. But one of the few consistent stars has been rover Reggie Floyd, who leads the team with 6.5 tackles for loss, including at least two apiece in each of the Hokies' three wins. Floyd has added 27 tackles, a QB hurry and a pick, too. As Virginia Tech's secondary finds its footing, he's been the the foundation of Bud Foster's defense. -- Hale

No. 25 Oklahoma State: RB Justice Hill

Until last weekend, running back Justice Hill's carries had been limited, in an attempt to preserve him for the entire season. But after a loss to Texas Tech, Oklahoma State unleashed him last weekend, and Hill piled up 189 yards on 31 carries in a win at Kansas. Hill now leads the Big 12 with 577 rushing yards, averaging a whopping 7.5 yards per carry. -- Trotter
