The first-team offense still has some work to do, particularly in pass protection after giving up two sacks against Miami. But Cam Newton, with a 58.5 career completion percentage, is showing he can be more efficient in Norv Turner's offense and Christian McCaffrey is showing he can run between the tackles (see 71-yard touchdown run). Newton completed 75 percent of his attempts (9 of 12 for 89 yards and a touchdown) in five series on Friday night as the Panthers improved to 2-0. He has completed 71.4 percent in two preseason games.
