I'm not sure how much I agree with your premise, or at least in whole. Think of the historically great Captain Comebacks in the NFL: Roger Staubach, Joe Montana, John Elway, Tom Brady, Peyton Manning...all these guys were great QBs on great teams, and I'm pretty sure these five are high on the list of most come from behind victories in the 4th quarter and/or two minute warning.
Now, of course, you can most likely find some QBs that fit your criteria. But overall, when I think of the greatest comeback QBs, those names above are what come to my mind. Someone like Dan Marino probably comes up, as I think he holds the record for most 4th quarter comebacks, iirc. His teams were good, but never great.
