John is lucky it wasn't a 15 rounder because he faded somewhat shockingly.
First half of the fight I thought was a bit dull, I think because of the power issue. As others have mentioned he has nice lateral movement. As John got tired and Juarez started to land it got more interesting and Juarez definitely took the late rounds.
Because of the better/cleaner work John had done enough in the early rounds to win.
I actully feel a bit sorry for Juarez, another night of not quite good enough.
