If it wasn't for The Ultimate Fighter, there would be no UFC.
Because of the success of the reality series and epic war between Forrest Griffin and Stephan Bonnar, the sport of Mixed Martial Arts rose from obscurity to one of the fastest growing sports of all time.
The fight between Griffin and Bonnar in 2005 was so good that it drew in 3.3 million viewers on Spike, and the rest is history. Fast forward 15 seasons, and TUF has given fans multiple memorable moments.
From fighters getting into altercations with one another to classic encounters between the coaches to great action inside the Octagon, the series has provided so much entertainment over the years.
Of all of those memorable moments, these are the 25 greatest in the history of The Ultimate Fighter.
