I wish they would think outside of the box a bit. Tournaments would be something that would get people excited again. They certainly have enough fighters in each division, and enough events to pull it off.
Imagine this LW tournament for example..
1 Ferguson vs 8 Poirier
3 Barboza vs 6 Diaz
4 Alvarez vs 5 Gaethje
2 Khabib vs 7 Lee
Set it up where each fighter gets $250k every time they show and the winner takes home $1 million + gets an additional $1 million to fight McGregor. Think any of the names above (besides maybe Nate) wouldn't sign up for that?
