The awkward part is Josh is super tight with Kyle Allen and Barkley, and a big role for the backup QB is to help the starter on game day and with preparation. (As I'm sure you know)
I am not saying you’re wrong as I do think QB2 is a liability if Josh ever goes down.
But I think Josh will have a big say for who he wants as the guy to help him get ready for game days, and Kyle and Barkley are his guys.
