The college playoff is not much different than the BCS. Set up by the same people to address the concerns of Power 5 conference teams picking a champions between them.
All of the strength of schedule concerns are a gate keeper that preserves the status quo. Take it for what it is, the College Play offs are the Power 5 intra-conference play off and championship.
It would be like a Canadian Football team saying we want access to the NFL playoffs and Superbowl.
