DC is an olympic wrestler who has qualified for the american team; its a world of difference vs standard MMA collegiate wrestler. Look at how Hendo shut down Rashad's wrestling. Then look at how DC tossed and slammed him like a child en route to a sub that surprised no one.
DC has huge credentials outside MMA, there aren't many athletes competing like him atm.
The most impressive thing is he's a short HW/LHW, at 5"10 or so, so he's pretty much always had a reach disadvantage. But he's still undefeated.
