Understandable, but flawed ....
Shockey was a cancerous tumor with the Giants .... slamming his helmet down on the field if Eli went to someone else with the ball, screaming and walking out of the huddle if his number wasn't called for the next play .... generally a really, really bad attitude and overall morale killer. I think once he got hurt, and the team saw how much more cohesive things were without him, they made a decision there and then to cut ties. Wrong behavior on the part of the Giants? Probably.
But Shockey always had an answer/excuse for his bad behavior. It was never his fault, he was just an innocent victim of the press, management, fans, media, etc. If he had ever manned up and acknowledged his own failings, the story may have had a different ending.
Shame of it is, he is a great player. Gives 1000% every time, not afraid to get super physical, has good work & practice habits .... there just wasn't any room on the NYG ego-wagon for Shockey, not with Tiki Barber & Strahan flapping their gums all day. The only difference between them and Shockey? Barber & Strahan gave respect to Manning, Shockey didn't .....
I'm glad he's working out for the Saints, he's a cool player to watch and seems really good for the team. Just keep an eye on him ....
