You would have to stop his takedowns to be a challenge to GSP. So would take Askren or Hendricks to develop the rest of their game. I don't think he likes to be hit and is now hurt standing, so hitting him on top is best.
I'm afraid that Kampmann and Condit are guaranteed 5 round fights with lots of lay a pray time in a 50-45 decision. I'd rather not see them and I don't see how he gets up for anyone at 170 after winning this so easily.
I think GSP-Franklin; Franklin won't get another shot against Silva, so its either this or focus on a title shot at 205.
