I'm really glad the UFC followed Holloway's idea to have Mark Coleman present the belt. First, I think they should try to push that brand with a different set of rules or scoring (I'm not sure it's actually possible with the NSAC) and have a previous BMF presenting the belt to the winner.
Now I suppose a lot of fans have no idea wether or not Mark Coleman deserves to be called a BMF (outside of what he has done with that house on fire thing), I can tell you that he does big time. To me he is a BMF primarly because he got on top of the heavyweight division, fell down big and climbed his way up to be number 1 a second time 3 years later. He also fought all the biggest challenges of his time: Severn, Frye, Rizzo, Vovchanchyn, Nogueira, Fedor, Frye again, Cro Cop, Shogun... He must have one of the longest run as a top 15 heavyweight as well. He impersonated passion. And with his own demons (alcohol), tragedies (randleman's death, heart attack) and heroic moments in his private life, he has all my sympathy and he's one the guy I associate the word Legend the most with. I hope we'll get to hear him a bit on the mic as well.
