I think he will be ok and as far as drafting another goes, that needs to be done now. I'd take one as high as RD2. You don't mess around with QB and if you're McDermott, you're a fool if you go into next year with just Allen and Barkley. So long as Allen throws a 2:1 TD:INT ratio I'd leave him alone. Doesn't need to be jaw dropping numbers. 3,200 yards 21 TDs and 10 picks or something in that vicinity and I'd leave him alone. That to me is plausible improvement.
