The very fact that Vick was even associated with illegal gambling may prove to be his undoing. Whether he profited personally from the gambling is irrelevant, as far as the NFL's personal conduct policy is concerned. My bet is that Goodell hands down at least a two year suspension after Vick gets out of prison. He may even make the ban permanent. Vick lied to Goodell and to Blank about his involvement in all this, and men in their positions don't like being made fools of. I'm sure the NFL is going to continue their own investigations into the gambling aspects.
The NFL has to send a message here regarding this type of behavior. I wouldn't be surprised at all if Vick never takes another snap in an NFL uniform.
