Hate to agree with Patrick . . . but this.
For what its worth the talking heads on NFLnetwork are saying his health is good, his dumping on the Houston coaching staff is what caused the dismissal, they didn't need him screwing up the atmosphere in the locker room of the Titanic.
He might be worth a look, his attitude could be better back home on a playoff team. He couldn't be expensive since the Texans are on the hook for a salary.
