I was shocked that Hatton could not walk down Collazo like Rivera was able to do for a good portion of his bout with Collazo. Collazo had the faster feet versus Hatton and that kept him out of a lot of trouble imo. Collazo is a good boxer just has no punching power and he can't fight on the reverse which is where I think Berto would have him. He would give him some problems with his slickness and accuracy but would eventually be run down imo. I know it was a long time ago but Rivera gave Collazo hell on the ropes which is where I think they would end up. Would definitely favor Berto here.
