1. Al is making a "competitive market salary"
2. The comparison is flawed unless you know Baylors endowment
Agree on #1.
As for #2, it's not about a university's endowment. That stuff is strictly for academics/facilities/faculty. Athletic departments are generally self-sufficient units, paid for by way of donors and ticket sales. The Athletic dept may occasionally ask for funds from the university's coffers, but that amount is usually small, just enough to cover any gaps in operating costs; they can't and don't depend on the university endowment for the bulk of their funding.
This is why you always see separate funding drives for athletics vs the general overall university.
As for Baylor, they have a lot of big-money donors. They're in the midst of building a nice new on-campus stadium funded exclusively by donors, the most significant of which is the owner of the Houston Astro's, who reportedly gave somewhere around 200 mil. So it shouldn't come as a shock that they can afford to pay Briles good money.
UM doesn't have a donor on the level of the Astro's owner, and most of our big-money alumni don't care about sports. That said, we'll have no prob opening up the purse strings if Golden succeeds here. I'm sure we could pay him up to 3 mil or better if he can get the team to an ACC champ and a BCS bowl game in the near future.
