Tonight's Ultimate Fighting Championship contest between Brock Lesnar and Randy Couture is being billed by some writers and fans (and promoters) as the biggest fight in the history of mixed martial arts. I think Lesnar has a higher ceiling than most people want to admit and he will do big things in this sport, but I'm going with Couture. He's one of the smartest fighters I've seen and his experience will help him against Lesnar. Lesnar is bigger, stronger and faster, but we still don't know a ton about him.
