This surprised me at first, but then I remembered a team can really only improve when switching quarterbacks from has apparently not persuaded the Bills' brass that he is the long-term solution at quarterback, although in his first full season as an NFL starter, he finished 10th in Passing NEP per play and 13th in cumulative Passing NEP. The dual-threat quarterback meshed well with Sammy Watkins, who worked through injuries and low volume in the season’s first half before catching fire from Week 9 onward. He finished as the season leader in Reception NEP per target among wide receivers with at least 80 targets.

Offseason acquisitions Charles Clay, LeSean McCoy, and Karlos Williams all struggled to stay on the field and had varying efficiency when playing. Clay looks like he could amount to a huge free agent bust, mostly limping through 13 games and topping 60 receiving yards only four times. McCoy was banged up early in the year but returned in Week 6 to surpass 68 rushing yards in eight consecutive contests. His rookie teammate in the backfield, Williams, scored nine times and led the NFL in Rushing NEP.
