No. Lets not get ridiculous. Fedor is still GOAT HW but, with years of can crushing after 2005, this is the fallout.
I made the Jones Jr. example. Years of being p4p best, clearing out division, and then, came the can crushing and coasting versus mandatory challengers. RJJ beat John Ruiz @ HW. He returns to LHW, fights Tarver, gets saved by corrupt American judges. Rematch = rd2 KO by Tarver.
Years of can crushing backfired on RJJ the same way it did Fedor IMHO. Those losses, Prime Fedor starches IMHO. Also, lets not forget the loses to guys on GEAR/TRT/ROIDs should be taken into account IMHO.
