Im not sold on Khabib being a draw yet, much like Holly became more famous after RRR but it did not equate to PPV success. Khabib is not good at hyping fights and pulled only 300k when he headlined on a card that had massive visibility owing to the riot. I think Khabib vs GSP does maybe a milly but vs Tony we are talking 500k or so, basically 2 Milly less than Conor Khabib. Bad blood sells and Conor is the most googled athlete on the planet, totally different realm than GSP or anyone else in MMA.
