This is the point that always gets me with guys like HA and JDG. You are absolutely right that the jury is still out on JP. We don't know. We can guess, we have glimpses, but we aren't 100 percent sure either way with the kid.
However, the one thing that is crystal clear, despite what HA and JDG may argue, JP is clearly the best QB ON THE ROSTER today. Better than Holcomb and Nall for what this offense demands.
So, if that's the case, there is nothing a fan can do but watch JP go and hope he develops. Because really, what is the alternative? Just more rebuilding as you pointed out.
Excellent point, Rock.
