300 still lacks a a real headliner and options available are pretty slim now that anyone Islam would fight is booked. Basically leaves finding a way to get Leon or Pereira to dance. Who do we think fills that main event? Or does Dana run with a solid lineup but no headliner for a century card? It's no 100 or 200.

At the point with the hype built around the main event, it has to be something that most fans don’t expect. 

Wild guess - Conor vs Nate for the new 165 belt

It would be controversial but they would pass over Chandler considering they’ve done this before with Khabib at MSG. Realistically Izzy vs Pereira 3 would still be great main event but I’m not sure if the UFC is looking for that from a marketing standpoint.

You think they'd go Nate over Chandler if they did a 165 belt? Part of me thinks conor for a 165 belt is what they're gonna do to make a splash, but its unfortunate none of the fighters they would target for that fight would actually be deserving title holders/challengers based on recent success
