Except it didn’t happen that way at all. Fedor first fought in the U.S. in 2006, and won that fight; fought in the US again in 2008 and won that fight; fought 2 more times in the US in 2009 and won those fights; it wasn’t until 2010 that he was beaten in the US.
Tbh, with people like Jones, Anderson, Werdum, and other guys that have PED failures, it’s pretty useless to talk about Father Time. Same with Hendo and TRT. It’s very difficult to judge the effects of time on people who take steroids to negate that exact thing.
