Ken and Tito are pretty much cut from the same cloth, in my opinion. Ken just doesn't like being on the receiving end of what he dished up for all those years. Getting beaten up by a basically younger, better version of himself had to be a bitter pill to swallow.
Hell, I think most of these pro-MMA feuds are just there to sell tickets. These guys all know and respect each other because, in the end, they are the only ones that have anything in common with one another. Pro MMA is a pretty small community and it takes a lot of sacrifice to make it that far. All of those guys realize that they are just one injury away from being out of the business, so I think they have a lot of empathy for each other when it comes right down to it. Will some of those guys have personality conflicts? Sure. I don't think you'll see Phil Baroni and Matt Lindland chilling out together anytime soon. But I think it's a lot less than it's sometimes played up to be.
