Are you suggesting that if only there were 8 games, OSU could have challenged Clemson or Alabama? I absolutely don't think so at all. And if we're honest, we all know that Bama and Clemson were head and shoulders above everyone else.
The same Clemson that plays in the garbage ACC, and who barely held on versus NC State and Syracuse?
Ohio State absolutely could have challenged either of those teams. Are you contending that Clemson is head and shoulders above Alabama who is head and shoulders above everybody else? Because those teams are great, but they aren't that great.
The Title Game shows that coaching is what matters. Ohio State recruits at the same level as these two teams, so it would have come down to whether Urban had Saban's number. Dabo did it, so it's completely possible.
