The projected cost will be north of $1M but a money game, like this year's foray into Lincoln, can pay for most if not all the cost of the stipend. I expect to see more one-and-done games with the bigger programs to keep BYU from dipping into the athletic department's annual net revenue.
BYU is in a good position to play the bigger programs around the country. We'll play at your field any time, for $1M+. With P5 teams making an effort to bolster their SOS and still play 7 home games, BYU becomes very attractive. Bring on 'Bama.
