Despite hip-hop’s prominence in the sport, the players who enter to songs from that genre are not as successful as those who prefer other genres, the analysis found.

I don’t know about the legality of all the stuff he used, but according to Jane Leavy a number of his treatments are so dangerous they are off the market. She describes one, Butazolidin, as “an anti-inflammatory drug prescribed for broken down thoroughbreds, so poisonous to living things that it was taken off the market in the mid-1970s. It had only one major side effect. It killed a few people”. She describes another, Capsolin, as having an active ingredient, “capsaicin, (that) works by depleting substance P, the brain’s pain messenger. It is the medical equivalent of hitting your head against a brick wall.” She goes on to describe its “atomic balm” effect, noting an instance when Lou Johnson wore an insufficiently washed Koufax sweatshirt and began to sweat, then had his skin blister and finally threw up. It too is off the market.
