Shogun KO's Rockhold. Luke's boxing isn't strong enough to keep Rua at bay for kicks...and Shogun was the better kicker as well.
Jacare subs Rampage. Elite BJJ guys got slammed, but rarely put out from slams and Jacare is better on the ground than Arona/Saku, has power in his hands to make getting on top easier.
Weidman grinds out Wand, I don't think he subs him, possibly TKO via GnP. Wand won't defend the TD and will have trouble escaping.
Chuck/Romero is the most interesting since Chuck at his best could 1-shot everyone and top wrestlers struggled to keep him down. Going with Chuck.
