It’s strategic. Some head coaches will accept average qb play so as to not mess with the psyche of a qb. Others will keep rotating qbs until one takes the job by the horns. Pruitt is the former. He knows damn well what he’s going to get in JG. A very average qb that hold the ball too long, is an inaccurate passer, and a guy that doesn’t have the athleticism to keep plays alive with his legs when the pocket breaks down.
You’ll almost never see a championship level team that doesn’t have a great qb. And in today’s game they’re almost all athletic guys. I can’t think of a single playoff team over the last 5 years that didn’t have a mobile qb. And please don’t try to tell me JG is a duel threat qb
