GSP will score early, easily, and often. But Jake will eventually get GSP down by late round 2 or early round 3 and keep dominant positioning on him for significant portions of two or three rounds. It will be very competitive, with only one round having a clear winner - rd 1 to Georges.
Very close decision, perhaps split. Many will be unhappy with the decision either way. I'll go with Mr. Shields.
I predict a very similar fight, but I think GSP will pull it out in the end.
Shields is no doubt GSP's toughest test at WW by some margin. He ain't no josh koscheck or Jon Fitch, his over all grappling ability is on another level compared to those guys.
I look forward to a very competitive fight and I hope Jake Shields finally earns the respect of the fans, far too many people don't give enough credit where credit is due.
