Nah, Jameis would have to be flawless in passer rating and converting most drives into TDs for him remaining the starter to be a thought. We aren’t sitting a 40M QB on the bench.
Carr hasn’t played poorly for his job to be questioned. He can work on getting the ball out quicker sometimes, but he’s been accurate and makes the throws. Just need more TDs and that’s a variety of factors with run game, blocking and playcalling. He moves the ball down the field at ease when he has average protection.
