Well I've already convinced myself that BJ will come to the fight motivated and ready to fight 3 rounds, then smash Rory and lick his blood off of his gloves.
Why do I do this to myself? I'm just going to end up hurt again.
More seriously though, BJ does have a pretty big advantage in every aspect except for cardio and size, including a massive advantage in grappling. I'm not saying.... I'm just saying.
