Jordan
Did basketball have a doping era? Talent + obsessive work ethic will get you a long way *if* you have enhanced physical recovery. Maybe that’s sometimes purely genetic. Kobe looked pretty buff for a few years post-Shaq (but not unbelievably so). Jordan was never huge but there’s more to chemically enhanced performance than bodybuilder physique (which hardly comes without specifically trying).
Why would an athlete *not* dope, especially if they felt it was long-term healthy and unlikely to be detected?
