Cam Newton not sure about coaches' plan to limit his running

Carolina Panthers quarterback Cam Newton doesn't sound as though he's fully into the coaching staff's plan to reduce his role in the running game this season. "I don't understand certain things,'' Newton said on Thursday, the first time he's spoken in depth to reporters since undergoing shoulder surgery in March. You going to expect a lion not to roar?'' Coach Ron Rivera said late last season the offense needed to evolve to take the pressure off Newton to run out of the read-option and to keep the 2015 NFL MVP from taking so many hits.
