http://www.sherdog.com/news/rankings/2/Sherdogs-Official-Mixed-Martial-Arts-Rankings-49719 If you look at the current list of HWs, Cain is literally the only HW with a serious wrestling background. Sometimes I genuinely wonder if that's why he's so successful. We kind of saw the same thing with Chuck Liddell during his reign -- he was the only guy with a serious wrestling background in his division and it made him unstoppable until Randy Couture, Rampage, Rashad etc. showed up. thoughts? opinions?
