Kerk pretty much rides/turns all of his opponents and gets ridden by no one. That is the definition of proficient mat wrestling. Saying anything else is disingenuous. In fact he out mat-wrestled Wyatt Hendrickson to beat him in the semis at nationals last year. I am not saying that Kerk's style of mat wrestling is exciting but it is one of, if not the most effective in this weight class. It is very reminiscent of Starrocci's mat wrestling.
