Baseball is a loping sport whose beauty is defined more by its subtlety. Its pace matches a summer evening but these days that’s seen as a negative. Football is as subtle as a sledgehammer. It moves quickly and always carries with it the hint of something really bad happening to someone. We like to see people crashing into each other and though we may cringe we secretly like to see people get maimed. Not much has changed in that regard since the days of the gladiators.
But it’s also a function of the teams. There was a point (decades old now, of course) when the Browns were perennial winners and the world knew it. As a franchise it got off on the right foot and moved forward for years in the right direction. Sure it’s come off its axis for at least the last generation but the most significant part of the fan base still has very fond memories of teams that actually won even if they ended up breaking your heart. That currency still spends pretty easily.
