Brock Lesnar vs Shane Carwin is a fight that I believe one day will happen. I think that Shane Carwin is the only heavyweight that can take down Lesnar other than Fedor. Go on youtube and check out Shane Carwin fights, better yet try and find this thingy the did on him cuz his fights do not do his skills justice if that makes any sense. His hands are BIGGER than Brock Lesnars heh
