I think Pacquiao may have slipped enough to the point where Lucas Matthyse would give him an extremely good fight, it certainly wouldn't have a dull moment regardless. As for the rematches mentioned I'm not sure, Cotto may well be capable of beating him at 154, but there is almost no way Pacquiao fights him above welterweight in my eyes. I actually think Joan Guzman could still beat Pacquiao as well, although of course that isn't about to happen. It's a terrible style for Manny the way he has looked lately though, and assuming Guzman still has his faculties he'd certainly have a great chance to win imo.
