His Olympic Freestyle finish isn't exactly unparalleled in MMA. Mark Coleman had the same finish and had a silver in the worlds at freestyle. Daniel Cormier actually made it one step further than Askren and finished 4th in the Olympics and had a bronze at the worlds in freestyle.
Askren's World Championship gold in 2009 wasn't in freestyle wrestling. It was in No-Gi Grappling. Not saying it wasn't impressive, but beating Nick Ring and Jacob Volkman in grappling isn't the same as beating the best in the world in freestyle wrestling.
Not trying to take anything away from Askren. He's a great wrestler and I expect big things from him in MMA. But his international wrestling career isn't exactly unparalleled in MMA, even when only considering freestyle wrestlers who are currently active.
Ah thanks for clarifying that, I need to read the fine print more.
