On the feet i believe Robert can hang with anyone especially when he is not cutting a bunch of weight. The guy is tough as hell and has a ton of power, if he could somehow stop the takedown id give him a shot. I know he would be giving up a lot of size, but him and Romero both looked pretty damn powerful.
Probably notJuice Jones would be shooting takedowns to lay on the MW for 5 boring rounds for sure.
