Have a true playoff . Make all teams join 8 football conferences They can all be 14 team conferences if needed and have an 8 team playoff.
I have no issue with them choosing OSU over TCU but there whole ranking process did no make sense. They had OSU 6th, TCU third. Beating a decent Wisconisn team badly should not have bounced TCU.
Its moot the system will say OSU was the best and they might be but it was a very flawed process.
They were 5th and then they beat a good Wisconsin team (ranked 13th) and won their conference championship while TCU beat a terrible Iowa St. team and didn't even play in a conference championship. I really don't see where the problem lies there.
Unfortunately, that's not realistic thanks to the old system making it so difficult to change around conferences, add teams, etc.
