The pick: Couture
The biggest fight in the history of mixed martial arts! That's what it's being billed as by some writers and fans (and promoters). It's a big fight and it might do the most buys, but it's not the biggest fight in the sport's history.
Heck, UFC 94 is on the horizon with an even better main event as Georges St. Pierre takes on B.J. Penn. Randy Couture-Brock Lesnar can't top that because neither fighter is at their peak. Couture's best days are behind him and Lesnar's are ahead of him.
Still, this fight is going to be great. I can't wait for it. 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 Randy Couture in this fight.
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. Couture wants to prevent Lesnar's takedowns, but that won't happen. I don't think anyone can stop Lesnar's takedowns.
I do think Couture will be fine on his back and that his dirty boxing in the clinch will be a difference maker as well. Couture can't treat Lesnar like another Tim Sylvia because while Lesnar is big, he's a hell of a lot better on the ground and is quicker than Sylvia. Still, the rumor is that Couture is planning to do rely heavily on his ground and pound and I think that is a strategy that could work for Couture.
He's not going to be able to submit Lesnar, but I think he could keep him on his heels with an aggressive approach. We still don't know what Lesnar is capable of. He destroyed Heath Herring with a devastating punch early in their bout and Herring never recovered from that. If Lesnar can't get anything going very early, Couture should be able to execute his game plan. Frank Mir got lucky and caught a much more inexperienced Lesnar with a quick submission. No one has pressed Lesnar so that will be the key for Couture. I like him in a fourth-round TKO.
