In the heavyweight forum, the Aoki vs. Penn debate is raging on again. However, a couple of the comments about how BJ's win at Mundials was years made me think. BJ's win was years ago now, and he has been training for MMA and not sport BJJ since then. However, he still trains with top notch BJJ guys. So, how much of his game(if any) do you think he has lost since he won Mundials? I'm just not good enough to know how much training it would take to maintain such a high level.
