Corto blatantly ran from both Margarito and Pacquiao. To some extent he also ran from Clottey and Mosley.
When somebody doesn't get hit often they call them a "runner" due to frustration. The fight Mayweather did the most "running" was against Hatton because Hatton holds too much so he did alot of backing up.
He's talking about his character and willingness to engage in exchanges. Obviously he knows Floyd is a mentally formidable opponent and is capable of going on the offensive.
I agree.....many people thinking Floyd will stop Cotto.........can“t see that happening..... IF Floyd stop Cotto will be big to him.....
