I have to imagine that at this point even he isn't expecting anyone to start him, so if he can be a good soldier about coming off the bench, then I don't really see a downside. It's him being a malcontent when not starting that's his problem stick around anywhere.
If he's finally been humbled & had to accept the reality of how much money his injury cost him, then I like it. You guys won't have capspace any time soon, so strong drafting & bargain contracts are going to need to be responsible for any further boosts to your team.
So it's all about the due-diligence that the organization has done into his current mindset, and their being content to cut him the instant he steps out of line & starts to subvert the lockerroom.
