Cam Newton showed glimpses Saturday night of why the Carolina Panthers made him the No. 1 pick in the NFL draft, from the strong arm that zipped the ball downfield to the mobility that bought extra moments in a collapsing pocket. He also looked like a rookie quarterback struggling with his accuracy. Newton led a pair of field-goal drives in his NFL debut, and Jimmy Clausen threw a touchdown pass to Greg Olsen to help the Panthers beat the New York Giants 20-10 in a preseason game. Newton, the Heisman Trophy winner from Auburn, twice failed to get the Panthers into the end zone on promising first-half drives. But he also brought some big-play potential to the league's worst offense last season and a franchise in desperate need of a fresh start. In fact, the loudest cheer might've come when Newton took the field less than a minute into the second quarter. "I was just trying to go out there and first off prove to myself that I could play on this level," Newton said. "After that first little completion, I started to get the juices flowing. It was like, 'Hey, I'm in the NFL,' and I started to get a little swagger about myself." Read more: http://sports.espn.go.com/nfl/recap?gameId=310813029
