The 2012 season marked a giant leap forward for many NFL quarterbacks.
While some were content to flounder in mediocrity or settle for being average, others elevated their respective games to new heights.
Last year, Bleacher Report's Matt Miller revealed the B/R 1,000, ranking the 1,000 best players in the NFL. Part of those rankings included the top 50 quarterbacks that the league had to offer in the 2011 season.
Let's see which quarterbacks improved the most this season, per the newest iteration of the B/R 1,000. Keep in mind, rookies will not be included in this list (sorry, Andrew Luck and Robert Griffin III).
