No, that is mainly it.
He gets to the NFL and literally from the very first day, he just didn't care. All he wanted was those millions and the fur coats and jets that come with them. He had zero interest in actually trying to be great and trying to help the NFL team that put its hope and millions of dollars on him.
I would play in the NFL for free if I could because I love the game... it just bothers me to see guys like him who have no respect for football and the competition between men.
Not to mention that I feel like when someone pays you good money to do a job, you're supposed to work hard to give them a return on their investment in you. Fair trade.
Having said all of that, "dead to me" is a little bit strong, I admit. There are others like him who have done the same, so he isn't the only one that I feel that way about.
