9. Thiago Alves
Record: 18-8
Promotion: UFC
Age: 27 years old
Reason:
Alves drops all the way from No. 5 in May to No. 9 this month following his loss to Rick Story at UFC 130.
“Pitbull” was once considered one of the elite welterweights in the world, but had recently dropped back-to-back fights to Jon Fitch and Georges St-Pierre.
Though those two are almost unanimously considered the best welterweights on the planet, the losses still derailed what appeared to be one of the most promising young welterweights in the UFC.
This loss to Story was disappointing, as it was his first loss to a fighter not named Fitch or St-Pierre since 2005 and will knock him out of the title picture for the foreseeable future.
