not it as sure, if fsu loses a game the acc isn't in that different a spot. If fsu and nd aren't in the picture I think it's a lock for two sec teams.
If the Big 12 just gets one team a year it could potentially be the most represented conference, but as I keep saying simple math and football media coverage don't mix.
well there's no way to do this but I'd bet a lot of money that no conference will ever get 2 teams in to the 4 team playoff. I don't think this playoff format will be around for much more than a decade and with five power conferences that would take two conferences to have their best team have 2 or more losses in a given year. That's not likely to happen
