In retrospect, perhaps asking Jamaal Charles to repeat what he did in 2013 wasn't fair.
That year, Charles was 27 years old u2015 in his absolute zenith u2015 and playing behind a fairly capable offensive line. He also had one of the game's best offensive minds, Andy Reid, calling plays for him in an offense perfectly designed for his talents u2015 against a last-place schedule, no less.
All of that added up to a career season in which the Chiefs went 11-5, Charles posted career highs of 1,980 yards from scrimmage and 19 touchdowns and generally performed so well that he got a new contract after the season, even though he had two years remaining on a team-friendly deal.
