In reading between the lines of everyone pushing for expansion after a single year of the 12 team playoff, I've come to the conclusion that they don't care how many teams are in the tournament so long as Alabama is included...for reasons.
I like the expanded playoff over the 4 team configuration, but I wasn't super crazy about the seeding, and I think the timeline/scheduling is a complete abomination.
I wrote in the other thread (The expanded College Football Playoff off to a rough start, which is where this discussion belongs):
"Either Untie the Quarterfinals from the Bowls or untie the Bowls from New Years Day. There is still nearly 2 full weeks between the 1st round and New Years Day as the [referenced] article currently proposes.
A 4-round tournament should last just over three weeks, beginning to end."
There was roughly an extra half week between each round of the playoff. It's totally unnecessary and defuses any momentum, drama, what-have-you, the previous round(s) generated. Also, I don't see the byes being much of an advantage at all. Certainly not over home field. The bye teams go roughly three weeks between games, are rusty, and play their first game after the aforementioned three weeks on a "neutral" bowl field vs an opponent who are game ready.
