Why would this matter anyway? BYU is recruiting college players. There are plenty of good college players that don't do anything (or even sniff) the NFL. Sure, high schools players that look to have NFL talent are great, but there aren't a ton of them and they're in high demand.
That said, I don't think Covey's a huge loss. Of all the positions where BYU seems to have recruited well lately, it's receiver.
