I don't agree at all, mate.
There are plenty of journeymen fighters who do nothing but take absolute beatings. Lot's of fighters fight through injuries that happen in fights. The punishment Tony has taken in fights isn't anything special. It's just highlighted a lot because his lack of skills sees it happening to him again and again on the biggest stage with the biggest exposure.
As for all the private life stuff, yeh, I just don't buy it. Billion dollar companies don't take any sorts of risks with liabilities like that. They wouldn't even do it for someone like Conor, and compared to Conor, Ferguson makes them basically nothing.
The UFC had a good look at Tony and his supposed mental problems and were happy to continue doing business with him. That should tell you everything. If he was anywhere near as "crazy" as he made out, they would have cut ties with him immediately.
Chris Benoit in the WWE is a good one to look at. He committed suicide and the WWE were all supportive and tributary at first, but the moment they found out he'd killed his family as well and had gone crazy they removed him from all their archives and never mentioned him again. If he'd shown any signs of unstability prior, they would have wiped him.
I've always just felt he plays it all up to get away with being a prick, and it's pretty undeniable that he is one. You can go all the way back to when he was on TUF to see that he was an asshole, and it's been regular asshole acts out of him since. Fans always give him a pass though. It's always "Oh, that's just Tony, he's just loco" or whatever bullshit.
I think it was telling how he reacted when that reporter, who had had good relationships with him prior, gave him props about overcoming mental issues. A good, normal person would have reacted differently. Tony told him to fuck off and put the character on. It looked like someone who didn't want to get props for something he knew was very played up on his part.
