Do you deserve full credit for beating a non-steroid version of a fighter?

Yes! pacquiao gets no credit thou.

some people say mosley did ran was out of it due to no steroids and marquez was fat due to no steroids does floyd deserve full credit for beating non-steroid versions of these fighters? is it not equal to fighting a past it fighter? They kept showing ads of Shane beating Margarito we all know Shane was juiced for that fight. He kept throwing bombs for 9 rounds without tiring suggesting Shane was on EPO. Then when he agreed to Mayweather we all no why he ran out of gas in 2 rounds. The roided version that fought Margarito in 2009 knocks out Mayweather in the 2nd or 3rd round. Mayweather in my opinon dosn't survive that 2nd round and who knows maybe that punch that wobble him would have put him to sleep that night.

There's no proof of either of those things I mean Shane went threw two tough camps and fought some he couldn't beat so.. That had a lot to do with him gassing plus his nerves Marquez was never gonna win that fight even he knew that lets be real He trained hard for PAC man cause he knows he has his number.
