No one will ever think that Floyd is doing steroids. What Manny is doing would be equivalent to as if Floyd was knocking out heavyweight.
i think the real equivalent would be floyd at WW for the last 6 years going up to 160 and 168 and beating martinez, abrahm, kessler, froch and having ward duck him because of some demand ward never asked before in his previous fights. floyd saying that he going up to HW and knocking them down is just a BS or an exaggerated analogy from floyd.
