How about an "evvah thang goes" level of pro sports? You could have that - roid rages, meth league, on-filed numbing, unlimited blood doping, all-out crazefests - and the "substance free" version. Let's say, for example, that was done in the NFL.
Then you could compare both the on-field and off-field results. All participation would be voluntary.
Undoubtedly, some clown in the drug-free version would decide that he could probably get an edge if he just broke that one little rule...
In any case, I have little sympathy... so long as the spectacle is good. I also am glad they're now able, legally to pay NCAA-ers. Everybody BUT the players has been raping that one for decades now.
