The BCS is now talking about a four team playoff and even Jim Delany is in. This is sort of about declining attendance (but not really), sort of about declining viewership (indirectly) and 1000% about this graph from a Neilsen "State of the Media" report on sports.
And then football:
Both the big basketball increase and big football decrease can be explained by external events. CBS finally realized it was the 18th century and split first-round games across four channels instead of forcing you to watch Local State U beat up on a 15 seed when Kansas (always Kansas) is suffering an incredible upset across the country. The BCS moved off broadcast to cable. But when paired with declining interest, the cavern between postseason formats screams "grit your teeth and do something literally everyone else wants."
BONUS: Nielsen lists the five most-watched games of the year:
1 vs 2 games, the Rose Bowl, the 3 vs 4 Fiesta, and random Michigan games not featuring awesome teams.
