In no particular order: QB, RB, WR, OL, and LB*.
I think #1 is wide receiver. Cooper is a #1 receiver, Gallup is a good #2 that possibly has more upside and Lamb has #1 potential.
Then they depth behind them isn't bad at all for guys competing for the 4/5/6 spots.
Then toss up between QB and RB for #2.
#4 would be linebackers, on paper anyways. We have two starters with high floors, with some questions, and the depth behind them in Lee and Thomas are solid backup/spot starters if need be.
I still see the offensive line as a strong group.
The left tackle is always in the running for being one of the best LT's, the right guard has been an allpro every year in the league and the Right Tackle has blossomed greatly last year to be known as one of the better RT's in the league.
3 set very good to elite pieces in the unit.
They have a solid competition at center hopefully, and Connor Williams is at least an average guard.
