Everyone knows that Bill likes to move on from big money stars, and both Kyle Duggar and Mike Onwenu will be getting pretty big paydays. I think with the rebuild, and how Onwenu has been playing at right tackle (top 3) he has to be re-signed to help any rookie qb we may get.
I could completely see Duggar walking with the emergence of Peppers and the drafting of Mapu. I also bet Josh Uche is gone. Adrian Phillips seems about done, he has barely played any snaps this year after leading the team in tackles 2 years ago. Trent Brown is probably gone too. No idea if weplan on riding it out with Mac for another year or go after a qb now, but he could be gone. That isn't exactly a secret though.
The NFLPA limiting the amount of offseason practices and full practices that teams can have is doing a huge disservice to the game and isn't talked about enough. It seems very obvious that many of these teams just don't seem properly coached.
