Well if he never goes to another team, the Detroit job isn't forever anyways. And may be cut short if the success isn't there. As I've stated, I don't see a cup contender. And I don't mean in 2 years. At this point, I don't see it 10 years from now.
Even if you want to give him ALL the credit for TBL, doesn't mean that happens for Detroit.
