The problem with the sport from the playoff era on is that everyone has attempted to maximize the postseason at the expense of the regular season.
BCS was a farce of a postseason product, but by nature of being a 2-team party, where massive brands were routinely sitting at home, the sport had to make the other games matter too. You had some Rose Bowls that were damn near as big as the natty. The Boise St-OU game is as (if not more) memorable as any semi final game has been.
I think college inherently is such a pure product that even with the mishandling of the last decade, it’s still an incredible one. But I do believe it’ll eventually stripped of most of its pageantry.
