Gator could run a show, but to do it he'd have to learn the lesson of why TRR even managed to be a success in the first place. It wasn't because of the personalities but because it was a blank slate that was there in time to cater to the mood of a readymade audience. It was always the audience.
All he would have to do is pick some cohosts who could help maintain a relaxed atmosphere between them all, and if he did it right then he could easily pick up an audience somewhere in the ballpark of what Ralph's show has had in the past few months. Assuming it's not all bots. He already sort of showed signs that he could manage it in the time when the Pillstream temporarily put Ralph out of commission. It would require a complete public heel-turn against Ralph to really follow through with it now though, and that's something he wouldn't have the balls or the sense to do.
