Just like Pacquiao needs finishes to be considered the best p4p fighter, right? His last two wins went to decision, but nobody is questioning his skill. GSP doesn't give up a single round over six fights, and you're questioning his ability to compete? The fact is, nobody comes even CLOSE to his ability in the welterweight division.
GSP is on a different level right now. Nobody can touch him, just like nobody can touch Manny Pacquiao.
Sure, we all want adrenaline and knockouts, but GSP is not a lesser man if he doesn't get knockouts.
Use your head for once. Five decisions in a row? How about five victories in a row, where he destroyed his opponents? There was absolutely NOTHING they could do against GSP.
