TJ Dillashaw
Two title reigns for TJ Dillashaw remain the highlight of his career, but there is a dark cloud over it all.
Dillashaw was forced to vacate the belt after failing multiple drug tests. He also lost his last fight, falling to Henry Cejudo for the flyweight belt.
In his first title defense, Dillashaw held the title for 603 days starting in 2014. He earned wins over Joe Soto and Renan Barao before falling to Cruz. His second reign lasted 501 days.
