I think that's an assumption with no evidence behind it. Possible, but there's no guarantee it would make all of the top lds kids come here.
If we were in the conference, but won 4-7 games every year, does byu really have anything going for themselves to get the recruits?
I know it's a good guess, but I don't think we have much evidence to truly say why each recruit makes his decision. And bring a losing team doesn't help much
