Kazushi is one of my favorite fighters, but I'm guessing that 1. He is maybe taking a rest from the top A fighters he keeps beating, or 2. Pride wants to maybe draw more attention to other fights other than his.
Personally, if I had beaten all these big names, I'd think of retireing just so I could say I did and not run the risk of getting beat
haha
Although Pit Dog would say that I lack gameness
Take care,
Ryu
