Basketball isn’t as demanding physically as cycling. You need to be fit but not to the extreme degree cycling demands. I would expect doping to be most beneficial in sports where pure physicality is needed. Marathon, triathlon, track running.
recovery help is where it's at these days i expect, in most sports.
there are obvious performance benefits for traditional endurance sports, but the testing infrastructure is pretty robust and the financial incentives are much less than those big team sports. it's harder to dope (and get away with it) and the financial pressure is less.
Sure, there's no drugs that will turn you into prime Messi. But there are drugs that will let Messi play like prime Messi for 90 minutes, 3 times a week, 48 weeks a year, which is incredibly valuable.
