It'll be either the Jets or Raiders. I am more than 75% sure he'll come back to the Raiders. He's a cali kid and is a loyal dude. The thing that people have to recognize about this is the contract was AUTOMATICALLY voided. People could be flipping out and Aso may have already made his decision to come back. He cannot sign a new contract until March or some s**t.
He'll get more money and get to stay home with the Raiders. Plus, it's underestimated how much he likes playing with the people we have here right now. I think a huge key will be if Seymour comes back. If he does, then Aso is coming back as well.
The only other option is the Jets. Play alongside Revis and for Rex Ryan. He will not get as much money and have to move out to NY, but maybe that's something Aso wants.
I personally feel he's coming back to the Raiders.
