6. Johnny Hendricks (UFC 200)
Pre-USADA, Johnny Hendricks was one of the most impressive welterweights on the roster. Indeed a savage fight with Georges St. Pierre, that most people thought he had won, sent the legendary Canadian into a four-year hiatus. However, when the mandatory drug-testing was brought in, Hendricks’s physical condition and results went into a sharp decline.
‘Bigg Rigg’ looked appalling at UFC 200. Without his beard, he looked very sickly and he missed weight at his 17th UFC fight. He’d go on a horrendous run of form before finally retiring in 2018.
