Lon did a ton to get fans to the games, including students. He didn't post as much on social media or brag about it, but he did it. Hell, the guy opened every practice he ever had to the public and was the most accessible coach on the planet.
OU is a far better job than most on this board realize. Our arena is old and we may not have a ton of NIL money, though that is speculation. But we have a hell of a lot better tradition than most schools, we have shown we can win consistently under multiple coaches and decades, and we are one of the bigger brand names in all of college sports. Of course we won't beat out any blue bloods for coaches, but if Moser bails, there will be a lot of very good coaches (or their agents) contacting Joe C before Moser packs up the culture wall and makes it out of the city limits.
