How could you not like Brock Lesnar? He has a great attitude, not cocky at all in his interviews, and I like how he left the WWE BS and actually is fighting now. No, he doesn't know many submissions and he's new to the game, but he doesn't think he's going to take over the UFC in an instant.
However, I do think Mir will catch Brock in a submission this fight. I think he needs more submission training, he won't be able to rely on his strength and wrestling the whole fight I don't think. I'm rooting for him, though. Either way win or lose, I think in the coming years when Brock gets more and more training he's going to be at the top.
