You know, if he was a first-rate LT, and I could convince myself of his mental fitness, I just might give him another chance. But his overall performance was very mediocre, and even if he was clean and sober, I'm not sure he could ever be any good. Add to that the risks in bringing him back (i.e. the media circus, the locker room dynamics, and what happens if he still sucks and I want to cut him now?), and it's clearly not worth it.
