Gsp had too many close fights for me. I actually like the fact he lost to Serra and Hughes because he avenged them good. Towards the end tho he had questionable wins against Carlo, Hendricks, DiazYou: GSP had a loss in his prime (It was actually 2, both were avenged) Therefore Fedor is the GOAT (got his brains beaten in during his prime and avoided avenging the losses)
Which fair play are good wins but he looked like he had had enough in those fights. It wasn't as dominant as we'd come to expect, and if he comes back he better have gone up a level not down a level (like Anderson did) or he's not in for a good time.
