I am excited to see Jiu Jitsu at a high level has returned to where it belongs Vinny 2012 I guarentee if Vinny had Jon's arm he would have taken it home with him. Gonna be great seeing him fight in the UFC again. Bummed Vitor didn't get the upset, a little bit of Hubber Guard would have gone a long way for him in that fight.
In my opinion in that brief moment of rubber guard game, he at least demonstrated well how the RG gives chances to work the elbows while limiting ground and pound
