If he didn't want to be here then he should have accepted when the team asked him to take a pay cut. If he thought the team was going to embrace cap hell and not have a starting QB he was sadly mistaken and an idiot to boot.
If he didn't want to be in New Orleans, he needed to work with the team.. He said no and the Saints, rightfully, said enjoy your sack of money because you're a Saint for another year. As I understand it, he didnt like that the Saints restructured his contract. To damn bad. It was the right decision for the Saints.
