even 75, IMO. This would stop elite teams from stockpiling as much talent as they do now.
Another idea is to limit teams to no more than 6 home games and/or mandate at least one true OOC road game per year. Many big programs play 7 or 8 home games every year, and only play an OOC road game every 2-3 years, or less. For example, Michigan and tOSU played all of their non-conference games at home this year, and Bama hasn’t played a true road game OOC in many years — since 2011, I believe.
This wouldn’t directly even out distribution of talent, but would help even out W-L records, give lesser programs better home schedules to sell to recruits and fans, and better separate contenders from pretenders.
