I'm sure there must be a specific (tight) window that you are referring to. But at least if you detailed your parameters and listed the associated facts people wouldn't be taking the claim as a reality of actual history...
As it is, it sounds like you believe 4x more players from U of Utah have played in the NFL than players from BYU.
All Time Numbers:
BYU 134 NFL players (6618 games)

Utah 131 NFL players (6051 games)

They've had more go to the NFL lately and have more current active players but your statements (word usage) make it seem like they have always placed 4x more NFL players which is not the case at all...
