Daniel Cormier is a considerably better fighter than Fedor ever was, so no, it doesn't prove that at all. DC could literally be in the middle of a heart attack and still not lose to an ancient Dan Henderson, hell, even Anderson Silva and Jake Shields handled Dan with ease, for the supposed best of all time to lose to Welterweights and Middleweights is a fucking joke. DC could come out of retirement at 60 and not struggle with a Fabio Maldonado tier fighter, and Fedro got his brains scrambled by him.
DC was a much better fighter and has a much, much better resume than Fedor. Outside of Nog and Cro Cop, which were two good but severely overrated wins, his resume is weak. Tim Sylvia and AA were his next best wins, Tim was honestly never good and AA was a glass cannon who could beat or lose to anyone on any given night. The rest of his resume is littered with beatable has beens like Mark Coleman and Kevin Randlemen, glorified journeymen like Kazuyuki Fujitia and Heath Herring, freakshow fights like Zulu and Hong Man Choi, hell, even pro wrestlers like Yugi fucking Nagata. Outside of the fights he lost, he struggled with guys like Fujita, Brett Rogers, Randleman, and Mark Hunt, guys DC would have bodied in his early Strikeforce days, let alone now. Fedor is lucky that he didn't come to the UFC in 09, because considering how Bigfoot took him down and beat the shit out of him, he probably would been embarrassed by Brock Lesnar too.
You overcompensating Fedor fanboys are the worst. You feel threatened and feel the need to make these stupid threads because you know he doesn't measure up at this level.
