If you look at the list, it seems to me to be a list of schools whose recruits are underrated. There are different reasons:
Utah, it seems picks over overlooked West coast kids and does a good job of it. BC is a bit of an East Coast Utah.
Iowa and Wisconsin are getting more good players, especially on the line, than people realize.
Miami and Florida are getting more high 3* somewhat underrated kids than the ratings services realize.
Oklahoma, looks like generally good evals in an era where they pulled fewer top kids.
NC State takes chances on very athletic kids, imo, and that can pan out. Not sure it’s about development. TCU also.
Not sure on Colorado and Washington. Some mix of modestly underrated kids, west coast coverage, lots of high 3* kids and decent evals, I guess.
