Is JaMarcus Russell Betraying Raider Nation?

I think JaMarcus just doesn't want to do what it takes to be a great Quarterback. Some guys when they get that huge contract in the NFL, they just happy with just collecting a paycheck. I think with is lack of commitment with is weight and the fact that he is partying it up in nightclubs, tells me that he just doesn't care. He is a lot like Ryan Leaf, he need to grow up a bit and understand what it takes to be a professional Quarterback. Maybe once the Raiders cut him, he will understand better.
