WHO'S NO. 1? THESE PLAYERS COULD CHALLENGE JOSH ALLEN FOR THE TOP SPOT

SAQUON BARKLEY RB, Penn State

A running back No. 1? (The last was Ki-Jana Carter in 1995.) Barkley, 5'11", 223 pounds, has gained 2,572 yards rushing and 563 receiving, and scored 30 TDs over two seasons. If Leonard Fournette and Christian McCaffrey flourish in 2017, Barkley will be tough to pass up.

SAM DARNOLD QB, USC

Darnold completed 67.2% of his passes for 3,086 yards, 31 TDs and nine picks as a redshirt freshman. The 6'4" 225-pounder has the arm, build and brains to have been the top quarterback taken this year had he been on the board.

DERWIN JAMES S, Florida State

No safety has gone in the top three since 1991 (Eric Turner), but James has the abilities of Jabrill Peppers without any question marks. The 6'3" 211-pounder can blow up linemen on blitzes and fly to the ball while defending the run or the pass.

ARDEN KEY DE/OLB, LSU

After accruing 14½ tackles for loss and 12 sacks last season, Key may be the top pass rusher in the 2018 class. His absence from spring practice for "personal reasons" raises some questions, but he says he'll be ready in the fall.

JOSH ROSEN QB, UCLA

Although there are questions about his off-field life, and he'll have to prove he's recovered from a shoulder injury that ended his 2016 season, Rosen has shown that he can make the types of throws NFL scouts want to see.
