I'm going to go out on a limb and agree with the premise here. I do think we have quality depth at most positions, and the offense has been given an injection of talent at many spots, including WR & RB.
I would like to have someone more experienced backup up AM.
I am skeptical of our current QB's competitiveness/confidence, and fear things could be similar to year 2, where many quality players suffered confidence issues like a flu passed on from patient 0. I hope it doesn't happen again, but if it does, the effects will be just as damaging as before.
So it seems Frost has set the ball on the tee and we have to wait and see what happens.
