Every team has a cap. Cap is just different for each team, and they're each bound by their own allocation. Yes, you'll have to overpay at some positions - that means it comes out of somewhere else. Overpay at QB, you're underpaying elsewhere.The positional cap is good in theory, but Nebraska(and FSU) dont have the recent success to set prices. Youre gonna have to overpay sometimes to get who you want when you arent producing results on the field and at the draft.
Texas Tech figured that out. If you arent the most desirable location/program/coach/etc, you have to overcome with Money.
Minchey and his Agent obv played Nebraska, but they also need to prevent that from happening in the first place
We may also have it in our allocation to "overpay" relative to the market at some spots (and likely did for Minchey, beating out multiple heavily interested suitors), but won't over-overpay beyond the allocated overpay.
Every team is doing this general framework.
