A starting quarterback isn’t going to feel threatened or turned off if the team decides to hand the ball off to the running back or full back, so why would they feel threatened or turned off if the team designs a run play for their backup?
I get your point, but it’s because the starter wants to be under center, running the offense and potentially checking out of the called RB/FB run when he sees the D exposed to the pass presnap.
How many big plays and TDs did Brees create by checking out of run plays? We’ll never know the exact number, but A LOT would be an accurate answer, I bet.
Even the play that a lot of Saints fans think secured the starting position for JW in the preseason game against Jax, was a called run that Winston audibles out of because he saw press man outside and a zero safety look.
How many times has Sean let Taysom audible out of QB power when he was inserted to run that play? None is my guess.
Not saying I don’t ever want Hill taking snaps from QB1, but to say there is no valid reason for QB1 to not like it is inaccurate.
