Maybe $6 billion would break Khabib Nurmagomedov's resolve.
UFC President Dana White explained recently that a reboot of The Ultimate Fighter was in the works, with Nurmagomedov and McGregor coaching on opposite sides.
"The Ultimate Fighter with [McGregor] is good attention for him," Nurmagomedov said to ESPN's Brett Okamoto.
This is good attention for him."
Money talks, and a Khabib/McGregor rematch is probably the biggest money fight the UFC could run right now.
