No they arent.
Its clear around 2008/2009 Fedor went into a decline. This doesnt have shit to do with PEDS. It had to do with age and wear and tear. He just couldnt grapple like he used to. The same happened to Henderson,Rampage,Diego etc. They HAVE to rely on their striking to continue their careers. Thats why Fedor lost to Blagoi in Sambo,and eventually lost in MMA too. Him refusing to sign with Dana can be excused,even though its unfortunate for everyone involved. He was used to much less restrictions on his comings and goings,and was making excellent money competing outside the Zuffa sphere,at the TAIL END of his career,after he done all he needed to do already. He also in that time pursued fights with the best he could get,Sylvia,Arlovski,Barnett,Couture etc.
