A bye week and the firing of their offensive coordinator didn’t make much of a difference for the Carolina Panthers (5-8) yesterday, as they lost their third straight game and fifth straight at home. Quarterback Cam Newton is now 0-3 since taking over the team’s starting job again last month, and the Atlanta Falcons (6-7) avoided a regular-season sweep to Carolina with a 29-21 victory. Newton completed 15-of-23 passes for 178 yards but threw a pick-six and had a lost fumble.
