UFC highest ever PPV - 1.6m, 2009 - Brock Lesnar.

2nd highest PPV - 1.1m, 2010 - Brock Lesnar.

3rd highest PPV - 1.1m, 2013 - Weidman vs. Silva II

4th highest PPV - 1m, 2010 - Brock Lesnar

5th highest PPV - 1m, 2008 - Brock Lesnar

So a WWE crossover star is the most popular attraction ever in the UFC. Since Lesnar's last fight they've cracked the million mark just once in four years, with Anderson Silva, who is the UFC P4P equivalent of Floyd, right?

Don't worry about boxing losing Floyd and Manny, you should be worrying about the UFC finding a new WWE star.
