I don't even really believe GSP will get the submission, more wishful thinking but I do think he cruises to easy decision victory. Two things to watch for, of course the power of Hendricks, GSP doesn't get hit a lot but when he does he doesn't seem to react well and the other thing to look out for is if GSP can take Hendricks down and if he does how well can Hendricks defend off his back.
Wouldn't even be surprised if every fight went to decision, think it's going to be a fairly drawn out, dull card.
Wouldn't be surprised if GSP retires with a victory, the rumors been floating around the media and I know someone who trains at Tri-Star and he basically told that while he doesn't know for sure if he will retire there is some substance to the rumors and there's murmurs about it around the gym.
