Noticed that Packers.com has Wooden listed at 273 lbs. I'm thinking that Wooden becomes primarily a DE in the new system and the top backup at DE to Gary/Van Ness. That I think makes it easier to move on from Preston Smith and leaves a potential depth chart of:
LDE: Gary, Wooden
NT/1i: Clark, Slaton
DT/3i: Wyatt, Brooks
RDE: Van Ness, Cox/Odumegwu/Day 3 draft pick
While moving on from Smith doesn't have much of a cap savings, I think the Packers are looking at it from a cash flow standpoint and whether they want to lay out $12M cash for a backup or if that cash is better spent on a signing bonus for a Love/Clark extension and replacing Smith with a day 3 draft pick if they don't think Cox or Odumegwu are ready/good fit.
Cambpell is a little different in that they don't have the depth there now to replace him. He has a smaller roster bonus than Smith at $2.9M, making it less of a risk to keep him on 3/15 and see if they can get an ILB on day 1 or 2 of the draft before cutting him. If they do get an ILB they think can start, they can release him post 6/1 if they need cap room for 2024.
