Ha! Cain is not a great personality of the sport. He has zero charisma and whilst he is a great fighter he has no personality at all.
Disagree completely, Cain is just as humble as JDS is and a great person to have sitting on top of the HW division. The UFC is very lucky to have them both, they're down to earth and similar to Fedor who let his fights speak for themselves while being the guy next door.
