He may not be relevant as a fighter but considering he is one of the top weight cutting and nutrition experts in MMA, I'd say he is very relevant. Either you're trolling, or you live under a rock.
it's just Roflcopter. He very rarely has anything positive to say about anything. Reminds me of that guy in class who always had a contradictory opinion to everyone else, just because.
With that said, he knows his shit.
