I love when fighters say this stuff, because it's always the same.
It's always super talented guys with no wrestling who get manhandled by gymrat wrestlers with the exception of Koscheck (after getting his NCAA wrestling title shoved up his ass by GSP) who cry foul.
Seriously, Penn, the Diaz bros. It's as though they figure they can just walk into the cage tie you in knots and walk out without breaking a sweat, and whenever they run into a guy who works harder than they do, it's obviously because that person is on roids and not because they are more focused and motivated.
That said, I'm not saying Roids couldn't be rampant, that's absolutely plausible, but coming from these guys it just seems more sour grapes than anything else.
