GSP is not a wrestler. He didn't wrestle growing up and he didn't wrestle in college. GSP trains wrestling now to augment his career as a mixed martial artist.
So consider this... Considering how well GSP implements wrestling into his skill set and how he takes down wrestlers (Isn't that kind of what they are supposed to be able to stop?) and destroys wrestlers....
If GSP HAD trained wrestling his whole life, he'd make Kos, Fitch, Hughes all look like they learned wrestling from watching Brock Lesnar on TV....
Sucks when someone who only 'dabbles' into what those guys made a lifestyle is able to train wreck them with it when accompanied by his other MMA skills. If they wanted to wrestle GSP, why are they in MMA?
Face it boys, you stepped up and were shut up.
