And the Big 12. And the ACC. In basketball. The Big 12 doesn't seed their tournament by division, but they schedule by division. Home and home against everyone in your division, one game against everyone in the other division. It doesn't look like the ACC does that though. Big 12 standings also aren't listed by division. It's just 12 teams, top to bottom. So divisions really only matter in football, and a geographic east/west split (esp. if you add Pitt) would have the historically best teams in the East (and would prevent the conference pipe dream of an OSU/UM title game every year). I don't know how else you would split it, though, unless you just threw teams into a hat
