14. Dustin Johnson
On his day, Johnson is one of the best golfers in the world. Yet Johnson has also struggled with substance abuse in the past. Between 2009 and 2014, he failed three drug tests. The first was for marijuana, but the second two were for cocaine. The latter drug in particular has dogged Johnson’s career and severely damaged his reputation. However, he rebounded to become the reigning World Number One in 2020.
Johnson’s love for a good party was notorious in high-level golf circles but infuriated NHL legend Wayne Gretzky. Why should Johnson care what Gretzky thinks? It was because he was dating the hockey icon’s daughter. Gretzky warned him that he would do his best to block his daughter’s relationship with him if he didn’t sober up. In sum, Johnson listened and now the couple has two children together.
