But when was the last time BYU made a big outlay based on the promise of future revenue, rather than already being able to finance it?

Very conservative financially means I doubt we'll do it immediately.

Also, there's some natural slowness in adjusting mindset. Same way that when you buy your first home after moving out of an apartment for years, you just can't imagine needing more space than 2400 sq ft. Because your perceptions are colored by your past experience. I'd imagine we'll be on the low end salary-wise for at least the first few years
