Montana and Bradshaw each have 4
Aikman and Brady have 3
Bart Starr, Bob Griese, Roger Staubach, Jim Plunkett, John Elway, and Ben Roethlisberger all have 2
Joe Namath, Len Dawson, Johnny Unitas, Ken Stabler, Joe Theisman, Jim McMahon, Phil Simms, Doug Williams, Jeff Hostetlier, Mark Rypien, Steve Young, Brett Farve, Kurt Warner, Trent Dilfer, Brad Johnson, Peyton Manning, Eli Manning, Drew Brees all have one
SO if SB Victories is all you look at there is the paramaters now looking at other things like overall QB rating Regular season, Post seaon etc. then it gets a bit murkey. It depends on what you value most as a fan. For me it is heavily weighted in SB victoruies then Post season win % and then overall QB ratings.
I haven't put all the numbers through the blender yet but I suspect using my formular Brady would be considerably higher then Manning. I will work on this and put out the rating shortly.
