Am I the only one who through Juan Diaz was pretty horrible in that fight then

Tactically, he was all wrong for 10 rounds. It's not like he couldn't of done more.... He could of done a whole load more. He was easily dominated until he actually put the pressure on... and basically applied himself.

So by that I can't tell a whole load by Juan Manuel Marquez' performance except that he will be perfectly okay fighting guys who don't apply themselves
