Then, you can watch the game from the beginning and skip commercials until you catch up to the live broadcast to start the second half as a continuation of your date night with HCBW.

Looks like a win-win situation to me.

For your Stake President friend - he should absolutely invite the visiting authority to watch the BYU game afterwards, regardless of whether the visiting authority is BYU fan. That's wholesome recreation and a good Saturday evening activity - plus, you're in the Pacific time zone, so it won't go too late.
