NFL's Players Conduct Policy

[CRedskinsRule]

First. As far as I know, no one is "guaranteed" a job, and certainly if you have committed a crime many employers will say see ya, rather than risk any potential liability on their end.

Second. Specific to Plaxico, as far as I understand it, right now he is unemployed. He is not signed with any team. If you go to an interview and have pending charges, I am positive your potential employer would consider that in his/her decision process. If the commissioner wants to put a ban on Plaxico, then I am sure the teams would prefer to know that sooner rather than later.

3rd, like Matty said, the NFL tries to protect its integrity, and generally speaking that is a good thing.
