.....ignorance/inexperience he fell for the bait...Roach belittled him all the way into the fight and you could see why. Santiagi must knew Cotto had no chance after round 7, but because of his verbals with Roach he was PRAYING for a 1 punch KO hence sending/sacrificing his man health and sending him out to slaughter...it was shamefull in human and disgusting. That was due to his personal ego/ not his judgement as a trainer....also shame on Cottos father...truly disgusting! Cotto showed what a proud warrior he was triying to fight to the end, he was in total retreat the last few rounds, it was a merciless beating by the Pacman who is one ruthless Mofo.
His uncle would have done little more, but maybe Emanuel Steward would have had a better chance. A fighter like Cotto needed a good solid strategic gameplan going into this fight, and it was a big factor.
He never really went for bullying in that fight though. Whenever he backed him up he just stood in front of him.
