Going to a 10 game conference schedule might make the conference more TV money, but I feel like it would take decades for that to matter within the actual sport. Big 10 teams would theoretically make more money than SEC teams, but the tradeoff would be more "good" teams finishing seasons at 7-5 or 8-4, while the same caliber SEC teams continue to finish at 9-3 or 10-2.
The public perception (which includes recruits) would be that, yeah you can watch more Big 10 matchups on tv, and maybe some Big 10 teams have nicer weight rooms or richer coaches, but the SEC teams win more games and send more teams to the playoff. Personally, that's what I want. I don't care at all about how many MORE zillion dollars we can add to our coffers, I want to win games.
