I would say all of them. The narrative that Butch built some monster is way off. All the decent WRs could be gone after next year. One proven RB after next year. Not much on the DL or LB. Average DBs. QBs probably worst in the conference. Dude has his work cut out for him. Year 2 might actually be worse than year 1 for him.
DL has strong stuff at the top. Move TK to linebacker, but they still need help. DBs seem to be a need. OL has a few pieces but needs a lot of help. QB is a need. RB is fine. WR, I don't know.
We have a lot of needs, but we need offensive linemen, linebackers and defensive linemen desperately.
Need depth at DL for sure. Vickers is gone. McKenzie, Tuttle, Taylor, Kongbo, Phillips are about it. Although it's probably best to move Kongbo to linebacker and just let him run at the QB
