I look at Fedor's decline as having more to do with his fighting style than having to do with some type of countdown clock we all have once we leave the Model T factory. Fedor's style relied heavily on his reflexes, explosiveness, and power, and he fought and won on the razors for a lot of years taking risks that modern fighters are now trained not to. When those things slowed in his early 30's (like they do for most football players who are out of the NFL by then), he became vulnerable trying to fight the way he always had. And another variable is injuries, which Fedor spoke of in his interview with "The Voice" as starting to affect him following the Tim Sylvia fight. Again, some fighting styles allow one to overcome injuries, but Fedor let it all hang out, and eventually age and injuries slowed him to the point that he let it all hang out there too long and guys could start capitalizing on opportunities that were not there before. The last variable is training, and with Fedor being cloistered the way he is, doesn't seem to have kept up with the rest of the MMA world, and fixing one's holes, and learning new skills and strategy are things that can't be neglected, especially for a guy who is slowing down and isn't as strong and explosive as he once was.
