JDS-I really think he can beat Cain again. He seemed to get over confident after landing a few on Cain, and started getting sloppy, moving straight back with his hands down and looking for one good shot.
Machida-not sure if he can beat JJ, but he did land a few good strikes in him in their fight, it was far closer than the Shogun/JJ fight IMO. I still think he has what it takes to beat all other top light heavies, including Gustafsson who seems to be next in line.
