I'm a huge Cotto fan, but I give Tony more credit than just his chin. His conditioning, heart, power and persistance won him that fight. I am very impressed with Margarito as a fighter. He walked through Cotto. I would love to see a rematch. Don't think Cotto deserves one just yet. I only hope that Cotto can do the same thing (if he gets a rematch) a little better and for all 12 rounds.
