I am a huge Marco fan and I definitely think he will fight better in the rematch. However, this will be the biggest challenge he has ever faced. While i don't think Pac has improved as greatly as many people on this board claim...there is no question that he is a tremendous athlete. Strong, fast, and a full pressure style make Manny a formidable force. Barrera has a big edge in ring intelligence and technique, but he is not a young warrior who can brawl for 12 rounds. However, you never count out a master boxer who still has something left in the tank....and unlike Morales...Marco still has something left. He has paced himself in the latter part of his career (by not just being a brawler) and has never had to kill himself to make weight like Eric. Add to that, that he is as much a cerebral boxer as a physical one...and he also will be a formidable opponent for Manny. Will he have enough to upset Pac? Not sure. But if anyone thinks it will be like the third Pac/Eric fight...they are mistaken. It will be an exciting fight and i hope it happens.
