QB's, ever. And has also landed two 5 star QB's in the past 15 years. If Byu continues to bring in 4 star QB's then we have evidence these big time QB's wanna play in Ty's system. If we watch Byu struggle to land QB's with many attractive offers that too will be telling. At this point it's speculation either way.
All I know is Byu has had James Lark, Jason Munns, Taysom Hill, Tanner Mangum, Jake Heaps, Ben Olson among others in recent years who spurned big time offers to play at Byu. We'll see if that trend continues or drops off.
