I'm already hyped up for the Lesnar/Carwin unification title fight. As Bloody Elbow pointed out, Mir/Carwin was the first UFC HW title fight (albeit an interim fight) where
both contestants had to cut to make 265; and Carwin/Lesnar will obviously be the same.
I was struck by a picture of Brock/Carwin in the cage after the fight. I've extracted part of it below. While Brock looked much bigger in the cage than Carwin, Shane's main weapon is the power in his huge hands. To that end, I was shocked by the disparity in hand size shown in the attached picture. Lesnar is a
huge human being, and Carwin's hands make his look actually small.
One thing is clear - you take one decent shot from fists like that, with the weight and muscle of someone like Carwin behind it, you find yourself on strange street. Brock better try to put Carwin on his back early and keep him there until the fight is over.
