I wouldn't be angry at all. But a CM punk victory is not at all like a Lesnar victory.
Let me explain: I respect Lesnar, his skill set, his his athleticism, and his victories. He's beaten legitimate top ten UFC HWs.
He's the real deal.
CM punk appears to not be athletic at all, he has no amateur record to speak of, and will be facing a hand picked opponent who doesn't seem to belong in the UFC to begin with.
I'll have no opinion of CM Punk if he manages to beat Micky Gall...it will mean just as much to me if he beat some other dude I've never heard of who doesn't belong in the UFC.
