I don't thinK Taylor would retire, but I could easily see Taylor's career going downhill pretty fast if he loses again to Pavlik.

Taylor's probably going to move up to 168, and he doesn't figure to be the type of guy who can effectively move up in weight. Taylor's biggest strength has always been that he's been bigger stronger and longer than his opponents at 160. As he moves up, the size advantage won't be the same anymore, since he'll be fighting bigger guys. And Taylor hasn't shown the skills to outbox a bigger stronger opponent.
