obviously we don't have a Manning, etc, and we don't need one, as we've seen time and time again where teams win a Super Bowl with an average QB, or far less than a franchise QB.
Time and time again? Let's look at the last 20 years:
Super Bowl XXVI - Mark Rypien
Super Bowl XXVII - Troy Aikman
Super Bowl XXVIII - Troy Aikman
Super Bowl XXIX - Steve Young
Super Bowl XXX - Troy Aikman
Super Bowl XXXI - Brett Favre
Super Bowl XXXII - John Elway
Super Bowl XXXIII - John Elway
Super Bowl XXXIV - Kurt Warner
Super Bowl XXXV - Trent Dilfer
Super Bowl XXXVI - Tom Brady
Super Bowl XXXVII - Brad Johnson
Super Bowl XXXVIII - Tom Brady
Super Bowl XXXIX - Tom Brady
Super Bowl XL - Ben Roethlisberger
Super Bowl XLI - Peyton Manning
Super Bowl XLII - Eli Manning
Super Bowl XLIII - Ben Roethlisberger
Super Bowl XLIV - Drew Brees
Super Bowl XLV - Aaron Rodgers
Pretty much all of those guys are HOFers except for Eli, Dilfer, and Rypien.
Edit: Add Johnson to the list of Non HOFers, but I would definitely say he, Rypien, and Eli are above average.
