FYI, "Key Fighters" are determined by the formula I use at MMADraws.com to rank fighters and to predict future buyrates/PPV numbers. A list for previous years can be found on the site as well on the main page under the "PPV History" tab. A summary of the year so far: 9 total shows 4,925,000 buys 547,222 average buys The number is already well ahead of last year's total and is on it's way to being the biggest year since 2010 (9,060,000). There's an outside shot that it could end up as the third biggest year of all time but almost no chance it passes 2009 for second place (8,025,000). The average per show is the 3rd biggest of all time right now but will likely drop with the next 3 shows expected to do relatively poorly. Even if UFC 194 does a million buys, it still probably wouldn't be enough to maintain this lofty average with the current lineups for 191, 192 and 193.
