Our quarterbacks all have good (or better) arm strength with relaxed throwing motions, and that they can all put some serious zip on the ball. None of them can be considered "noodle armed."
If another QB steps in to replace Carr for any reason (blowout leads, etc), then I feel quite happy about the fact that the whole playbook should be open to them, that they can make all of the throws.
