I think he could end up with the raiders - not at QB though. Probably like a slot receiver or part time RB/dual threat. Sounds like the vikes need a QB. Personally I think he sucks as a QB (and as a person, obviously) and he did the Falcons a favor by going to jail. They'd have never be able to trade him, and benching him could have caused riots. That Ryan kid looks like he may work out ok.....
I agree with other posters - he served his time and has paid dearly. He deserves a chance to earn a living. But my prediction is that he will end up like his younger brother in a couple of years - a broke, extremely talented athlete who wasted all of the opportunities presented.
