Haha how old are you? They brought eyes to the sport, but from who? From people who only care to watch THEM fight. From people who only care for the WWE-style drama that doesn't belong in any actual professional sport. From people looking to see trash talkers and brawlers rather than professionals and skilled MMArtists. They may have brought a lot of money for the few PPV's they were in, but did they produce enough to break the necessary >$100m annual PROFIT needed to break even after WME went into debt purchasing the UFC?
Now, come back to me with PROOF that they brought some great new fanbase into the sport (or even just in the UFC) and how it's "good for the sport" before trying to say they brought "new eyeballs".
