By about a 2:1 margin, most people say Lesnar.
That's what the Vegas odds reflect as well. Although Couture opened as a favorite, enough money has been bet on Lesnar in the couple of months since the fight was announced that Lesnar is now the betting favorite. As strange as it is to say, the heavyweight champ and Hall of Famer is expected to lose to the guy with the 2-1 career record.
In fact, the most common answer I heard when I asked people who they expect to see win was some variation on the seemingly paradoxical, "Lesnar doesn't deserve a title shot, but he'll beat Couture."
I really don't agree with either part of that. The UFC was put in a strange position when its reigning heavyweight champ retired, only to come back at a time when its interim champ already had another fight scheduled. I have no problem with Lesnar getting a title shot under those circumstances.
But I also don't think he's ready to beat Couture. For as big and strong as Lesnar is, I just don't think he's a complete enough fighter to beat a guy like Couture just yet.
