Well the one trick comment is made to compare to Collins being called a swiss-army knife. Obviously Kennard had value to us in run defense with some pass rush ability but his moderate salary was still not enough for us to keep around with his limitations.
If a backbreaker on D last year was lack of good coverage from our LB core, we set out to upgrade in FA with Collins. Another thought is that Collins had more splash plays as a simiar role to Kennard while being better in coverage.
Kennard’s limited skill set still got him a nice payday from a team that maybe will make him “splash” more as a rush backer in a 3-4. He will set the edge and rush without more expectations? I guess that still has value, especially if he’s been healthy all along.
