This is the main part of Boise's schedule every year: Idaho, Idaho St., La Tech, Hawaii, San Jose St., New Mexico St., Utah State, Nevada, Fresno St.
Then, add in a couple more cupcakes like: Bowling Green and So. Mississippi and one Pac 10 team [last year it was four win UW, this year it is soon to be four loss Oregon]
Voila, 10 wins or more year in and year out.
No doubt they are well coached, and no they are not heavy on 4* guys, but they also recruit better than their main competitors, so you can't say it is all coaching.
tcu is the same story.....good coaching and better talent than the weak sisters who comprise the main part of your schedule. That's why Patterson wouldn't be a slam dunk at KSU just as Hawkins wasn't a slam dunk at CU.
