17. Bob Baffert
The most famous racehorse trainer in the United States, Baffert has had extreme success. His stables have seven Kentucky Derby victories to their name. But not everything is as it seems with this shadiest of characters. His horses failed 31 drug tests over the course of 40 years. In sum, that’s an average of one per year. Somehow he maintained credibility until 2021.

Then his horse Medina Spirit failed a drug test after its Kentucky Derby win. This led to other races suspending Baffert’s horses. Furthermore, he attracted the ire of Former President Donald Trump. Trump sneered at Baffert’s misfortune and labeled the horse a junkie. To be fair, he wasn’t far wrong. Baffert tried to say a groom urinated on the horse’s hay after consuming cough syrup. Right.
