The leeches that is his management and coaches are too much ingrained in Fedor. Judging by the whole M-1/UFC hoopla that happened (and continues to happen to a certain extent) several years ago and his demeanor, it sounds to me like they have that man brainwashed. I would love for Fedor to swtich camps, but politics (both political and religious) play a major role in this. Do not underestimate the power of the red curtain, nor the power of his clergymen.
