I think the fight was so exciting because paulie showed great durability against the stronger man.
If Paulie had not shown such hearty it would have been an early nights work for Cotto.
One thing is for sure Paulie cannot punch for shi.t.
He stuck a lot of blows on Cotto and didn't make a dent. Sure he made Cotto miss but he didn't have the power to take the wind out of Cotto's sails and thats why Miguel had gas in the tank in the 11th and 12th rounds.
