I agree with this 100%. I say keep it at four teams, with a human element we will always argue about something. Next up will be a 12 or 16 team playoff until we get to 24 or 32. I actually was a fan of the BCS because computers did not care who you were, they just looked at the data. Iowa was #1 by all the computers prior to the Stanzi injury in 2009 which sparked outrage because we are Iowa.
