I think the way GSP is ducking fighters ALL the time is a little shady. I mean, if you're training hard for a fight, having someone backout on you is way worse for you than having them thumb you in the eye, hold the fence, or even strike you to the back of the head.
When GSP says, "He couldn't handle my riddum." What he really mean was, "He can't handle the riddum of me telling him I'm going to fight, then backout, then tell him I'm going to fight him again."
That is just plain stressful, and is no doubt what got him the victory over Hughes, and we'll no doubt see him victorious against Serra now.
Seriously, I like GSP, I just wish he would fight fairly squarely.
