Ignoring the fact that Ron Rivera has absolutely ZERO involvement with team finances and therefore him benching someone because of some future cap projection is beyond retarded - the rest of your statement is so bereft of logic as to be laughable.
Williams was moved down on the depth chart because our coaching staff felt that Stewart better fit what we wanted to do as a team schematically, no other reason. They had already paid him for the year, therefore if he was the best back you play him. You don't bench him to prove you don't need him.....that's just fuging brain dead logic.
As much as I hate to agree with him I kind of do. I also believed Dwill was benched so that the team could see how they looked without him. Of course it backfired with Stewart being hurt.
