It's actually not that great of a takedown for MMA since you don't have control of the person. Hendo got up from a bunch of the slams as well.
Olympic wrestlers don't put much emphasis on control after the takedown, so they often don't have great control. They got good takedowns, but that means fuck all when your opponent can pop right back up.
DC & Yoel probably got less than a combined 10 minutes of top control time in their entire careers since being in a major league like strikeforce/UFC. And most of that is Yoel vs Tavares. If you remove Tavares it's probably less than 5 minutes of top control.
