i'm a Reem fan and hope he smashes Brock, but Brock's cardio is the one thing that scares me in his fight. He was cutting from 290 in all his fights before his first surgery and dude just never seemed to get tired. Hopefully if Reem does gas his jiu jitsu will play a factor and he can get a hold of a limb if Brock ends up on top. Would be crazy if Reem could submit Brock's giant ass neck with one of his crazy guillotines.
