The premise seems to be that he was not motivated last year, and that this year he will dominate to prove all of the doubters wrong.
Here's the problem with this logic....as a soon-to-be free agent, how would that have not motivated him last year? I am one of the biggest Moss supporters, and I would be ecstatic if he came back. The problem, however, is that I think his poor performance had more to do with his inability to create separation from defenders. We know he can catch the ball, he just doesn't have the separation to allow him to make those catches anymore.
