Brett Favre

Brett Favre’s ironman streak of 297 consecutive starts stands 104 games longer than the next-closest quarterback on this list, John Elway (193), and his three consecutive MVP awards (1995–1997) make him the only player to win the award in three straight seasons since the NFL merger. He threw 508 touchdowns in his career—a record that stood for 15 years—and his 72.2% completion rate in 2009 at age 40 outperformed the average quarterback age 40+ by 10 percentage points.
