Regarding playoff site selection, someone posted the official rules over at AGS, so I'm copying it over here:
Site Selection
With regard to first-round, second-round, quarterfinal and semifinal sites, in addition to the criteria listed in Bylaw 31.1.3.2.1, the NCAA Division I Football Championship Committee shall consider the following additional criteria when selecting playoff sites:
1. Prospective host institutions must submit the following minimum financial guarantees, which shall be 75 percent of the estimated net receipts as submitted on the proposed budget:
First round – $30,000
Second round – $30,000
Quarterfinal – $40,000
Semifinal – $50,000
2. If the minimum financial guarantees are met, the committee will award the playoff sites to the top five seeded teams.
and then someone gave a good example that illustrates it:
If you bid 30K and your ticket sales are enough that 75% of it is 31K, they take 31K
If you bid 212K and sell 180K in tickets they are taking 212k leaving you with a major loss.
I don't know what our ticket sales usually bring in, but considering we're pretty low on the overall average attendance list, we can't be bidding very high if we don't want to possibly take a huge loss.
