I dunno man. His record ain't all that bad if you take a closer look at it.
Lost his first two in the UFC, OK, whatever.
Won his next one. Lost a split due to losing points on groin kicks. I can't remember the fight, so I don't know if it was flagrant or whatever, but everyone knows you can sell them (Ask Matt Hughes about that when he lost the title to GSP).
Won his next two, and then got a NC for having weed in his system (another win taken in a BS way). And then won his last one. If you take out NC, which I think everyone can agree is horse shyt, that's 5 wins in his last 6.
