I tend to do better judging fights right off the bat. After reading and watching hype for awhile I get caught up in the "oh this IS going to be an epic fight!" and my opinion gets slanted. My initial reaction with this fight was that GSP was going to smash Shields and I'm sticking with that. I think the big factor in this fight isn't going to be stand up, wrestling or BJJ. I think the factor is going to be pace and cardio.
GSP has cardio for days and Shields does not. I don't think you can really train for the level changing and pace of GSP. I think it'll be a fight that slides more and more into St. Pierre's favor as the fight goes on. I think many people are going to be surprised when Shields gets ahold of a leg and drive St. Pierre into the fence for a couple of times but it won't last and the peppering jabs and level changes will burn Shields out. I don't think GSP will finish him 'cause Shields is a tough dude but it will be a decisive performance.
