Yes he left for money...He talks about it in the Smashing Machine. UFC was close to folding at that time because they lost PPV.
As far as Semmy...has wins over Mezger,Kondo, Funaki, and former UFC champ Pete Williams
And besides that...I'm not praising them as his greatest wins....it was in reference to your stupid comment comparing timelines between him and Silva. Everything progresses. In his reign, Fedor was better than any other HW out there, and he was fighting in the org with the best heavies. During Anderson's reign...he was the best MW. But you tried to downplay Fedor by comparing direct dates with Anderson, instead of comparing accomplishments based on level of competition. They were at their peaks at different yrs.
So if you want to debate who was better, at least use logical criteria and reasoning.
