Everyone on here is raising some good points but they neglect one. Kerr was never really a fighter. He fought for a living, but he was not a fighter. When he was young and able to dominate due to his skillset, which he was miles above most at the time, he was the best. However, once he tasted defeat, it separated him from people who grew up as a fighter, like his friend Mark Coleman. I love Kerr, he is one of my favorites and as a wrestler I emulated him to a degree, but by his own admission his heart was not in the sport. Kerr is a good example of why some people can have limited success in MMA while being a monster in collegiate wrestling. Kevin Jackson and Brock Lesnar are two other examples of when you win it is awesome. When you lose, and you are getting punched in the face a lot, it is no longer the competition, but the paycheck. Granted you could make the case that Kerr and Brock made it to the pinnacle, but it was against competition that was considerably inferior to their skills, but changed rapidly with increased competition. There is a difference between wrestling and MMA, and when you lose in MMA, it is sometimes the only way you notice it.
I hope that is cogent.
@Nathan LaMontagne and
@fightiq might be able to explain it better,
First off, thank you for thinking of me, I'm flattered.
I have some specific opinions on Kerr specifically.
He wasn't just more skilled, of course he was stronger, but it was his speed that was just ridiculous for someone his size.
Another boon to his success was, He was very clearly an intelligent guy
I do completely agree that Kerr wasn't a "fighter" in mindset.
It's something he was great at and could make a living doing. It was more something that he fell into.
I think the biggest downfall of Marks Career, outside of the obvious crippling opiate addiction and turbulent home life...
I may be wrong but I think in a lot of ways Kerr was a very sensitive person.
The opening scene of the smashing machine I feel you can hear it in his voice when he's talking about gauging someone's cut, he sounds almost like he feels guilt and some pain for saying that is what it takes to do this sport (especially then)
I personally think that effected him a lot, the pressure and nerves (something that's been an awful problem for myself in competing)
He told the story on how he couldn't keep the tiniest amount of water down without heaving.
You mix that with withdrawal symptoms and rehab and a very troubled relationship... That's ones thing.
You add the fight against Fujita to that (and Igor v Kerr 1 to a lesser degree)
He got physically hurt bad, but I think the mental and emotional toll outweighs it by a lot. I luckily never lost in MMA so I can't even fully empathize with it. But even losing meaningless Judo matches I felt absolutely devastated and felt like dying. That's how bad it gets for some people. And keep in mind that is over referees calling it. I didn't get pummeled and bloodied.
I think the thing that points to it is he did recover from the Igor fight and went on to look great. It was ruled a no contest which I think gives that excuse that you aren't limited, they just broke the rules.
Whereas the Fujita fight... A complete beating after trying your best for your body just to give out and scream for oxygen.
I actually liken Kerr to GSP in mentality, Kerr very much could have changed his style to a safer, more consistent style.
Both clearly smart guys that have noticable vulnerabilities. The extra turmoil in Kerrs life is where it seperates the two.
TL;DR if anyone hasnt... watch the smashing machine. Still the best media in all of MMA
