Moving Davis means he needs to adjust his body for the position, including adding weight. as such, this feels to be more than a temporary move. If we experience issues there, he can move back. But I sense barring unforeseen events, this is a perm move.
I like the idea of taking an athlete and giving him an opportunity to play rather than hold a clipboard. But we'll all see in a few weeks.
As for building depth at qb, we hear about a battle for starter. More, Diaco has recruited a qb every year, so the pipeline feels better (to me) now than it has in many years.
