20. Edmond Tarverdyan
Tarverdyan was incredibly lucky. Ronda Rousey walked through the doors of Glendale Fight Club and became a UFC champion. She ran through women in mere seconds as she used her armbar submission to great effect. The former Olympic judoka became a global superstar in the process. But questions remain about Tarverdyan’s influence.
Rousey’s final two fights saw her suffer back-to-back knockout losses. Meanwhile, Tarverdyan attracted massive criticism because of his coaching advice. He encouraged her to strike with Holly Holm, a former champion boxer. Meanwhile, his advice against Amanda Nunes was pointless. To sum up, his decision-making was some of the wackiest ever.
