Quarterbacks

Lock is an underclassman to keep an eye on. He really finished the season strong as Missouri won six straight games and he had 43 touchdown passes to 12 interceptions.

Running backs

So Barkley is the clear No. 1, and after that it's going to come down to testing numbers at the combine. Harris is one of my favorite prospects in this class. Johnson is banged up but has had a breakout 2017 season.

Fullbacks/H-backs

Bawden is the best bruising fullback -- he's 6-foot-3, 245 pounds, and paves the way for fringe Heisman candidate Rashaad Penny.

Wide receivers

Lasley has come on as Josh Rosen's No. 1 target, finishing the regular season with back-to-back 200-yard games.

Tight ends

Smythe has only 26 career catches for the Fighting Irish, but he has some receiving skills. He might be a better pro than college player.

Offensive tackles

Harrison is a Texas transfer who also spent time at a junior college. Jones has really improved from last season.

Offensive guards

O'Connell is massive -- 6-foot-8, 354 pounds.

Centers

It's not a strong center class past the top two, and Ragnow was injured in October and hasn't played since.

Defensive ends

Green is probably an end in a 3-4. He has eight sacks this season. Jelks has 15 tackles for loss and 6.5 sacks.

Defensive tackles

I have four tackles in my 25, but it's still early. We still don't have accurate sizes on Wilkins and Vea, who are at the top for now.

Inside linebackers

Kiser has 9.5 tackles for loss and 134 tackles this season.

Outside linebackers

Holland has nine sacks this season after limited playing time in 2016.

Cornerbacks

The cornerback class could be deep. Stewart is a versatile player who will help a team in the return game.

Safeties

Reid, whose brother is NFL safety Eric Reid, has five interceptions and 88 tackles this season.

Kickers and punters

Townsend and Scott are definitely draftable prospects.
