I liked Heyman's final comment that the world of wrestling needs to get it''s collective houses in order. if UFC/MMA continues like it has, it's going to knock wrestling right out of the loop.
IDK. Amateur wrestling has been a huge part of MMA since Dan Sevryn won his UFC championships back in the day (the over-the-head suplex he reversed Joyce Gracie's Jujitsu triangle choke with was crazy) and I look at both professional wrestling and MMA as an extension of amateur wrestling (pro wrestling being the more entertainment part of it for sure, but still applying the same techniques, tactics, strategies, and principles of amateur wrestling, while MMA is taking amateur wrestling and incorporating it with other skills found in other martial arts)
So I think there will always be room for both.
Besides, I think Heyman's last comment was about ratings and PPV buy-rates between the two (if wrestling wants to have the same ratings and buy-rates success that MMA now is receiving it has to up its entertainment value more by giving the people what they want to see... and I don't think he necessarily meant doing the hardcore stuff Nowie, just entertaining booking and good use of potential like he did with the RVD's, Jerry Lynn's, Lance Storm's, etc, in ECW and the Lesnar's, Cena's, Hurricane's, Guerrero's, and cruiserweights, when he was head of creative for Smackdown and pulling in better ratings than RAW was at the time)
