Since Trent Dilfer gave teams with bad quarterbacks reason for hope by winning it all, 19 Super Bowls have been played.
They were won by Tom Brady (6), Peyton Manning, Ben Roethlisberger and Eli Manning (2 each), Aaron Rodgers, Patrick Mahomes, Russell Wilson, Drew Brees, Brad Johnson, Joe Flacco and Nick Foles.
Most of those winners are top-tier franchise quarterbacks. Johnson and Flacco were effective veterans. Foles was a backup who performed at a level never seen from him before or since.
You can win big without a star quarterback, but the odds are against you.
