It’s been called the most important fight in UFC history. And for that matter, it may be the most important fight in MMA history in terms of opening the floodgates for the sport to reach a wider audience. A week from today, Forrest Griffin (19-7 MMA, 10-5 UFC) and Stephan Bonnar (15-8 MMA, 8-7 UFC) will be inducted into the UFC Hall of Fame, and they’ll go in largely on the strength of their first fight in 2005. Griffin and Bonnar met in the light heavyweight finals of the first season of “The Ultimate Fighter.” In the live finale, the two slugged it out for three rounds.
