I'm not sure Fitch is the most important, but he certainly is one of the most interesting cases.
To most fans, he's boring to watch. He doesn't finish fights, and completely shuts down his opponent from ammounting any offense what so ever. While I find it impressive, I also don't find it that entertaining. I don't find him boring to the extent that alot of people do, but I won't apologize for saying Fitch isn't exciting. What I like about the guy though is his attitude. He's a hard worker, a humble guy, gives 110% every time, and is honest. He's not a suckup, and he's not going to kiss anybody's ass. The last part is what really bothers Dana. From a business perspective, I love Dana White, but from a personal perspective I think Dana is a jerk. Dana really only cares if the fights are exciting, and I can understand that from his point of view. However, instead of promoting Fitch as the talented fighter he is, Dana trashes him each time he gets the chance, just because Fitch isn't exciting, doesn't kiss Dana's ass, and has admitted that he doesn't like or respect Dana. Guys like Tito who have had issues with Dana in the past are easy to promote because tito has a big, charismatic personality. He puts asses in seats. Fitch doesn't, but consistently puts up huge results that are very hard to argue with. Dana's trapped with Fitch, and that's why it's interesting. A guy who always wins in impressive fashion, and does his job beyond well, but has admitted to not liking you, or respecting you. Dana doesn't respond well to not being respected. But if he cut Fitch out of spite, people would be all over his ass, and the UFC would take a big hit from sports media as a whole.
I love Fitch, and I love how he drives Dana insane.
