Not long ago the UFC announced the signing of an immensely credentialed Greco-Roman wrestler: undefeated lightweight Mark Overgaard Madsen.
I explored Madsen’s accomplishments in-depth at that time, but the basic gist is that Madsen has medaled at five World Championship tournaments and took silver at the 2016 Rio Olympics. While he never reached the top of the podium, he was a major threat for over a decade.
Fighting exclusively in his native Denmark, Madsen went 2-0 in MMA back in 2013-2014, which an insanely impressive feat considering he was still winning major tournaments concurrently, then went on to reach the World finals in 2015.
