That's right - Frank Mir is a black belt in Brazilian jiu-jitsu. That sound you're hearing is every keyboard warrior who's ever doubted him frantically deleting any offensive tweets they may have sent to the former Champion. His skill and technical ability go way beyond just being able to knock guys out, which is the painful stereotype associated with most heavyweights.

Mir is in a league of his own when it comes to dedication to his craft, and his phenomenal training under Ricardo Pires is a huge sign of that. If he can amalgamate all of his experience and everything he's learned over the years, there's a very likely possibility that he could go on one last strong run in the UFC.

It's not a guarantee, but you should never say never in the fight game. We conclude with a fact that Frank may not want to be repeated.
