I think his problem now is that while he has seemingly been vindicated after his main accuser was completely discredited, he still has other cases out there that haven't gotten as much pub.
So the worry for teams now is that signing him would get those other cases propped up and pushed to the forefront. Then comes the media circus and you might just have to cut him again.
Idk, I still think the right team should sign him. Texas Rangers seem like a good fit.
