"Sure, luck means a lot in football. Not having a good quarterback is bad luck."
—Don Shula, Hall of Fame head coach
The success of an NFL head coach often depends upon the player in charge of running the offense. A quarterback's proficiency, in turn, can be greatly enhanced by the guidance of an outstanding coach.
Bill Walsh and Joe Montana. Vince Lombardi and Bart Starr. Tom Landry and Roger Staubach. Bill Belichick and Tom Brady. Chuck Knoll and Terry Bradshaw.
Each formidable pairing combined to win multiple Super Bowls, as did Shula and Bob Griese. Shula also got to the Super Bowl with Johnny Unitas and Dan Marino.
In case you didn't notice, every person listed in the previous paragraph has been inducted into the NFL Hall of Fame, except Belichick and Brady, who will certainly join them in Canton, Ohio, one day.
This brings us to John Harbaugh and Joe Flacco, who have been at it together for 10 years with the Baltimore Ravens, going back to the 2008 season when the head coach and quarterback were both rookies. Though this tandem's viability as Hall of Fame material is open for debate, there's no arguing the Harbaugh-Flacco combination is a winner—as evidenced by 10 postseason victories, including Super Bowl XLVII in February 2013.
And they're not done yet.
