Video: Check out the new format, bad blood on 'TUF 21: ATT vs. Blackzilians'

If the trailer is a real indication of what’s to come, the UFC may have given “The Ultimate Fighter” series exactly what it needed: a real overhaul.

This past week, the organization unveiled plans for the 21st domestic season of the long-running reality show, which celebrates its 10th anniversary this year. And “TUF 21: American Top Team vs. Blackzilians” strays from the usual format.

In fact, the show’s location, coaches, team format, training schedule, living arrangements and even the grand prize have all undergone changes. And there’s plenty of bad blood.
