Sadly, Lesnar is the next biggest draw. Khabib and GSP might be big if it happens soon while the luster is still on Khabib.
Jones and Cormier at HWT would sell well. especially with a decent under card.
The fight to make is Diaz vs. Diaz. They are crazy MF's and for a check, they'd do it.
On the outside change that Lewis wins, Lesnar vs. Lewis could be big.
