and that's FBS D1.
It's silly to compare today's college passing game (success markers), to our glory yr QBs.
That said, any current BYU QB that can achieve a PER in the mid 150s will almost certainly have good to great success (by our offensive standards). Especially if they're a decent running threat(not Taysom level but Jaren, Zach level: approx 300-400 net yds).
