I don't see how this could be good strategy.

1) Can BYU seriously hire enough of the football talent out there as to reduce the chances that other teams will succeed?

2) Is BYU so prized a destination among football players that they would be willing to sit on the sidelines at BYU rather than get more time playing, at another team? Consider that they also want to attract the attention of NFL scouts.

Google doesn't have any of these problems -- for many candidates, it is the NFL, and there's no real limit on how many people can "play".
