Josh Rosenthal, ref of the Brock vs Carwin fight tells why he didn't stop the fight in round one when Carwin was all over Brock:
"He took some hard shots when they were against the fence," Rosenthal said of Lesnar on ESPN's MMA Live. "He was looking for a way out. He was blocking some punches. At one point he tried to spin to push Shane away and took a couple shots. And then again, went for a deep half guard position and took a couple more shots. When he curled up after that is when I commanded him to fight back, which at that point he did, and then he went for feet on the hips to push Carwin away and was able to get to his knees. He pretty much ran with it. He heard -- he responded to my commands."
“Part of our strategy and the things that we worked on in camp limited (Carwin’s) ability to get into those standup exchanges and relied a lot on when he did get (Brock) in a vulnerable position with Brock being up against the cage with his head down,” Welch said. “I just think (Carwin) made the best of the situation he had and he may have gassed out when he put himself in that position.”
“Either you have it or you don't,” said Welch. “But he has a ton of heart, a ton of balls and a good chin. You put those three together and you get the heavyweight champ of the world. You get through that and that's the difference between a guy that puts his tail between his legs and a guy that will jump up and do damage.”
Brazilian BJJ trainer Rodrigo Comprido talked to GracieMag.com about Brock and his next opponent Cain Velasquez:
"Brock is every coach’s dream. He doesn’t complain, he always pays attention to what we’re teaching and he’s a born athlete. He has abnormal strength and speed. The sky’s the limit with him, and he’ll continue to evolve for a long time. He’s a grappler, so he loves training on the ground, likes training as a whole a lot. And one thing you haven’t seen yet is how he has an aggressive guard. He’ll surprise a lot of people... [Cain] Velasquez is really tough, quick and technical. It will be a really tough, these days there are no easy opponents. The guy beat Minotauro, there are no better credentials than that. It will be a great bout, everyone will see. But I’ll bet my job on Brock!"
