Do what Marquez did. Weather Pacquiaos early attack, concentrate on the body, use the jab, and put Pacquiao down because if this goes the distance he ain't winning.
I think Cotto should work his powerful jab alot. Miguel Cotto's left jab is such an underatted weapon and by him being the bigger and stronger man he could really control the pace of the fight with this and Pacquiao still has balance issues IMO Cotto pumping out 2-3 stiff jabs could put Pacquiao even more out of postion.
Cotto is better than all 3 of them and would beat all three of them even if hey were the same size. You'll find out on the 14th.
Simple, beat the **** outta him. Cotto needs to walk in behind a very strong jab and hit the body often. Also Manny eats plenty of right hands so Cotto should throw lead right hands as Manny is bouncing in. That will either hurt him or drop him cause of his off balance. He needs to cut the ring off and throw punches as he is moving in or Manny will just flurry his way out of danger. He really needs to rough house him and show his strength.
defense defense defense....he has all the offensive tools but still takes too many flush shots....he limits that while still being himself...he wins...but thats easier said than done.
