If Brissett is Walker’s best friend, that helps, as does our DL being better. Yes, they have Garrett but their DTs are smaller dudes who could not stop the run and Clowney is gone. This is the perfect place for a LB to sign a 1 year prove it deal and then get paid (not quite the same scenario but Holcomb was one of the few off ball LBs to lock up a 3 year deal)
Walker likely starts over Barton at MIKE if he plays like his 2021 self. He’s a cerebral player who has played that MIKE role longer
