Mosley will more than likely succeed against Collazo. I just don't think Collazo has the right stuff to defeat Shane. The biggest liability for Mosley is that he is 35 years old and sooner or later he will look like an older fighter. If he does grow old in this fight he will lose pretty bad. Collazo is a very solid boxer and will make him pay if he shows up old and slower.
Mosley has been a very "youthful" older fighter. He is always in shape between fights and lives clean(as far as we know).
However, I don't see Mosley having any of these difficulties yet...so he should get a win in this fight...Maybe by a Ko(he's that much better than Collazo).
PBF may be in Mosley's future....we will see. If it happens it better happen soon because Mosley is getting OLDER and he is a SPEED/FLURRY fighter. He has to have speed to be what he is.
sugar shane is 35, remember what happened to RJJ at 35, or how much winky wright has slowed down because he's 35. collazo is getting better with every fight, shane is getting further away form his prime every day. mosley is not bernard hopkins, he doesn't use technique to win, he depends on speed. collazo will beat mosley
