Because the casuals in the combat sports world has proven time and again is that they have more money than brains. Conor might be irrelevant as an elite fighter but he's still on the roster, casuals know his name, and Conor hasn't been a professional in years. Do I want to see Max succeed at Conor's expense? Why the fuck not?
If Topuria keeps being a diva, or Max can't get a title shot for whatever reason, I'm down with watching Max beat the shit out of Conor as an alternative to pass time.
Paddy's a fast-rising LW, no clue what this Arman fool is trying, Gaethje is still hanging around and Max has a lot of miles on his face and body. I don't believe LW Max has significantly improved enough just by avoiding the nasty weight cut alone. We've already seen Topuria crack that chin once, and I don't see a rematch playing out much different.
