IMO, who cares if the NFL suspends the guy. Personally I think suspension is not really the answer, but I do think a paid leave of absense would be right and entirely acceptible. It is common practice for police officers under investigation to be put on paid leave. Same for Teachers in most cases. Due to unions, contracts, etc. The NFL can't just suspend the guy "because he may make them look bad".
It's too late for the current crop of bad boys in the NFL. I think the new commisioners crackdown on "thug life" is a good thing for the NFL, AND all of the future prospective NFL players, and even college ball players who won't ever make it to the NFL. Think about it, if these kids know that if they do wrong that they won't make it to the NFL, they will clean up their act pretty well.
