I went with Lesnar only because he handled a veteran of the sport. The match wasn't even close and it was total domination. The only flaw is that Lesnar showed a great lack of experience by refusing to take his back, and advantage of certain positions. At the same time, it was also a smart move. Being as green as he is, attempting to take Herrings back could have backfired, and the fight may have ended differently. Good job by Lesnar.
I would have GSP in second, proving that he was able to defend the belt by dominating Fitch in everyway.
