Dennis Green has a theory that Michael Vick will not return to the NFL and will end up playing in the United Football League.
That may be somewhat self-serving because Green is one of the coaches in the new league. But Green also is a former NFL coach who knows how things operate behind the scenes, and he said the "league kinda sets their own rules," implying that there might be some kind of agreement by NFL teams to stay away from Vick. That could be a valid point.
