I agree that BYU needs to get an additional FBS payday home game each year. But, 8 home games is a pipe dream.
Look, the athletic department has $6-8M profit most years. We can take $1M or so of the profits from the previous year to buy the extra home game. We'd probably come out ahead, because we would have an additional game's worth of ticket sales and TV revenue and save on the travel expenses for the 6th road game. The majority of P5 schools do get 7 home games per year. This will help BYU to make up some of the P5 financial gap. And the FBS home game should be teams like Toledo, NIU, MTSU, NMSU, etc.
With independence and a national fan base, BYU wants some road games. After the second payday home game, the next step is to get an *annual* neutral-site game as part of a "Pioneer" or "Beehive" series, similar to Notre Dame's "Shamrock Series." Get ESPN to commit to show it on ABC and the ticket sales and TV revenue could be split with the opponent (or, go to NBC, FOX, and CBS).
