And what cmg said, it goes both ways, so it kind of is fair. It evens out in a way. Not every team is gaining transfers. Someone also lost that guy first, thus dropping their points down. And I doubt many schools have had as many "transfers" as BYU lately, so it's even more in their favor.
It's not about being accurate and spot on with the "#40." It's just about the clear difference that, give or take a few spots here or there, we would see. Jumping 20+ spots from guys who are making up a 3rd of the class total in points, all things considered, is huge.
It's a weird thing to say because of missions as well, but it's not worth the hassle of getting all technical. It's clearly a big boost regardless.
