I was thinking the same thing. There is a gigantic gap between the top 10 or so teams and the rest of the field. It almost feels like the way women's college basketball used to feel, when UConn and Tennessee were so far ahead of the rest of the field that it rendered the sport uninteresting.
There are definite tiers within the ACC and Big 12.
ACC haves -- Miami, FSU, Clemson. There's smallish second level where UNC, SMU and Louisville can probably pump enough money in their programs to compete with that top tier. Then there's everyone else.
In the Big 12, Texas Tech seems to want to play the big-money game. You might be able to throw Iowa State on that level too. But for the most part it feels like the Big 12 is going to be a one-bid league most years.
It's going to reach a breaking point. Northwestern can't compete with Oregon and Ohio State. Mississippi State can't keep up with Alabama, LSU and Georgia. There's an entire swath of schools in the P4 alone that feels like I-AA to the big schools' I-A.
