Cam Newton's 77.5 passer rating is the lowest by a reigning MVP since former Tennessee Titans quarterback Steve McNair posted a 73.1 mark in 2004. His 45.3 completion percentage since Week 11 is the third-lowest by any quarterback in a six-game span since 1991, per NFL Research.
Whether the root cause of Newton's disappointing production lies in his mechanical flaws, a crisis of confidence stemming from his Super Bowl 50 failures, his injury-ravaged offensive line, an inconsistent ground attack or -- most likely -- a combination thereof, the Carolina Panthers understand their approach must change in 2017.
