Say what you want about him on a bad night and not really physical but few have had an psych out effect and critical analysis of opponents as Hopkins. Before the bell rang he was climbing into a guys mental make up.

Jones jr too. He took more than a few normally sturdy guys and just "shocked" them with fast power and swagger in boat loads.

Mental despaire can pave roads for a guy and lead to physical break downs, just put a guy in doubt prior to the first round. Once a guy doubts himself he's already playing catch up.
