re: Vote for best playoff number 4,6,8,12,16

4. There’s a reasonable chance of having 3 undefeated power 5 champions that all deserve to have things decided on the field. That’s why 2 is insufficient. The potential for 3-4 undefeated teams was the only flaw with the BCS championship game. The probability of 5 undefeated teams is low enough that I think it’s negligible.
