From an interview with MMAyou.com:
MMAyou.com: Here’s a question from one of your fans that I thought was a really good question. Why did the Pride judges hate you so much?
Mezger: You know, I’ll tell you truthfully man, I wouldn’t play ball with them on certain things. They wanted me to do certain things that’s just not something that I’m gonna do. It’s against my, kind of my moral code and I think it pissed them off because I’m not gonna do some of the stuff that they wanted me to do. And I knew the moment that I disagreed, that I wasn’t gonna play the game with them on that that things were gonna go south for me there.
MMAyou.com: Can we get into anymore then that or should we just leave that at that?
Mezger: I don’t really want to get into the whole thing you know it’s just that they were wanting me to be creative in some of the guys I fought. They wanted kind of a different outcome for the fight and when I refused… They started with the whole talking about it and I was like, “Guys, I know where we’re going with this. Before you guys say anything I’m not gonna do it. I know where we’re going with this conversation and that’s just not something I’m gonna do”. I knew when that happened that I was gonna have to knock guys out. It was kind of a drag. I knew that any of those tough close fights were gonna be… I knew it. (Editor’s note: Mezger lost 3 split decision matches in Pride and Pride officials wanted him to fight an overtime round against Kazushi Sakuraba despite his contract saying that the fight would only be one fifteen minute round with no overtime. Mezger left the ring after being advised by his trainer Ken Shamrock to do so and the president of Pride FC later made a public apology to Mezger for the miscommunication.)
Dealing with the Japanese too you know in dealing with that stuff. They have no real sanctioning body. There’s no athletic board overseeing them or signing judges or any of that kind of stuff. You know they can do whatever they want over there and they often do.
