If durability, victories and playoff appearances are the necessary attributes, then Flacco — the leading passer in Baltimore Ravens history — has few peers.
During a week in which the Pittsburgh Steelers (6-3) face the Ravens (7-2) without injured quarterback Ben Roethlisberger, Flacco is preparing to make his 74th consecutive start for Baltimore. He has never missed a game since being drafted in 2008, and under his direction, the Ravens are the only team to reach the postseason in each of the last four years.
No other quarterback in NFL history has ever led his team to the playoffs in his first four seasons.
