They'll basically only take one if he's an absolute "must take" guy, so there's certain highly ranked LB's that BYU simply isn't pursuing hard. And this is the opinion of a highly recruited LB for the 2023 class.
Not that that changes the "perception" of certain recruits.
The fact is BYU is getting into more higher rated recruits than previously since the Big12 announcement. That will continue to grow.
