He's our Rich Franklin at 65 KG.
He has a rating of 8-9/10 of every stat or attribute that might matter. When he can utilize his balance he can win those matches. More accurately, when an opponent who is truly elite in any one or two categories cannot stick to a gameplan exploiting that, he has a good chance to beat just about anyone.
Against Dest, he was out-toughed. McKenna had a very low wrestling IQ moment in the last ten seconds of the match, and I think he was still a little shook/fuzzy from being put to sleep.
