Correction: The $4 million added BYU “money shot” described by Forbes writer Jim Williams, is more accurately described as a $240 million added value over the span of the Big 12 contract with the new 12-team league beginning in 2024.

Still doesn't factor in BYU's own share (i.e. the first $27M / per year or whatever that they had to add to not be dilutive to begin with), but at least getting the additive part right now.
