As i originally stated in the post you quoted, there never should have been any scrutiny directed at Roshkopf, because he did nothing wrong. It does not matter why a fighter feels they are no longer able to continue and I am not sure why you felt the need to make a distinction when there was none.
Rohskopfs head coach (Robert Drysdale) refused to call the fight after being asked to do so nine times. He publicly humiliated his athlete and ruined his career. That same coach was
kicked-out of the UFC (then a fighter), before USADA testing was enacted, for serial PED abuse. Also, Andre Galvao recently
said he took a dive in his 2007 ADCC match against Drysdale and the ADCC head
said he had evidence Drysdale participated in more than one fixed match. So this guy has never won fairly.
The MMA media and the smug commentators publicly humiliated this kid and ruined his career for having the courage to take a fight against an opponent with three times as many fights as him on 10 days notice. Michael Bisping (who did most of the Roshkopf bashing), said during that broadcast " Robert Drysdale was doing everything he could to instill some kind of fire, some kind of passion to get him off the stool and go out and fight and to be honest i think it was the right thing"
Yet, in 2014 when Drysdale was kicked out of the UFC Bisping
said this about Drysdale " Fucking Drysdale he can kiss my ass..... You're a cheat, and now he failed his IQ test. Not only is he a steroid cheat, but he's fucking stupid.".
Bisping and Jon Anik are both pathetic for how they handled that situation and it is also why the MMA media will never have a shred of credibility.
