AP poll has no bearing on playoffs.
Well, we know that's not true, Kristy.
The AP (and Coaches) polls set the conditions for the conversation. What conversation? Practically every conversation.
Who do ESPN, CBS, Fox, and all the other media key in on during the week? Teams in the (AP) Top 25.
Who get all the storylines? Teams in the (AP) Top 25.
What games get aired on the national networks? Those involving teams in the (AP) Top 25.
So we're all inundated with this conversation, for weeks on end, before the CFP committee ever meets for the first time. We, and they, are conditioned to look in a certain direction, to expect certain things, to measure in a certain way.
Oh yes, the AP poll has HUGE bearing on the playoffs. And it has already begun.
p.s. Please don't take that to mean that I'm agreeing with the fellow who says some mythical "they" are locking the SEC out of the playoffs except for Alabama. There is no monolithic "they." The AP poll voters don't think or act en masse, they're a bunch of individuals each casting their own votes.
