At lhw, I think the best chance rests with Machida or Gustafson, and yes I realize he beat Machida pretty soundly, but Machida probably has had the best single round against Bones since Bonnar fought him...and no, I'm not counting Vitor's near armbar.
At HW, I think Jones settles near the top, but I don't think he beats JDS or Cain. Overeem, bigfoot, hunt, struve...I can see them going either way.
Just my opinion here. I'm interested to see who they line up next and what the future holds. I'm not a Jon Jones fan, but I respect the hell out of his skill set as a fighter, dude is a p4p great in the sport.
