The knockdown was lucky punch that caught Collazo on his heels, he looked at the ref sttraight away after he hit the floor and showed he wasnt hurt. Collazo landed the better cleaner punches throughout the fight whilst Ricky was content to walk straight forward, straight back and get hit constantly. Hatton showed nothing thats gonna make him a superstar in America. I saida while back that Ricky was only Frank Warrens 'golden cow', I think Frank knew Rickys level and thats why he fought lightweights and hand picked aging welters most of his career in Manchester. Now Hattons went to the US and been exposed in my opinion.
