Let him grow. Confident. Option ready. Accuracy. Better presence. Lateral movement with speed.
He might not be ready but neither is Taylor. Throw him at slot. If he doesn't like it. show him the door.
Enough is enough.
Also, expecting Taylor to be your QB til he has exhausted his eligibility will basically have wasted Brion's as well. Give it to the guy who is a natural Qb and let his instincts take over when needed. Taylor doesn't have Qb instincts. You know it, I know it, The world knows it.
