Brock's shown his whole career that he doesn't take a punch well though, even back in the Couture fight, Brock was flinching away from Randy's short little punches, and Randy is not known to be a hard puncher, the Carwin fight could easily have been stopped IMO, nobody would have complained if it had been, if I remember right Brock actually turned his back and ran from Carwin's punches the same way he did against Cain.
