That's just not a recipe for sustained success. Meyer did not have a 2 QB system in '06

Tim Tebow was a situational QB as a freshman. He had certain packages that were for specific situations. Chris Leak was the recognized QB1 on that team.
ND used something similar in '21 with Coan and Buchner.

You know the saying about having two starting QBs. It has pretty much held true most of the time. I would be very leery if that became the situation with this ND team.
