Had we taken Rosen, Costello might have gone to U$C. He stated that Stanford not taking a QB in 2015 was one of the reasons he chose us.

This is the point I think we're forgetting here.  Costello isn't here if we had taken Rosen.  Perhaps we sign someone else in that class, perhaps we don't, but we had K.J. locked in so early that I don't think any other quarterback recruitment advanced too far, if at all.  Heck, if we take Rosen, we might have struck out entirely in the class of 2016, as I'm pretty sure we never offered the other top QBs in that class.  We probably still land Mills, but that gap might well still be there in the "we land Rosen" hypothetical--just pushed back a year.
