I think Pruitt favored JG's experience. It is now up to BM to close that gap. That said, Pruitt benched JG multiple times this year and definitely gave Maurer a shot. Barring injury, Maurer probably starts the last 2/3's of the season.Pruitt has shown no inclination for playing any other QB than Guarantano. If he stays for 2020, battling Bailey for the backup spot isn't in Maurer's best interest if he can go to a team with a competent QB coach and have a legit chance at starting in 2021.
Pruitt would like to have a QB claim and own the job. That he continues to bench JG... indicates he's aware JG isn't that guy right now.
