Cam Newton followed through on his pledge to participate in drills at the NFL scouting combine on Sunday, and he won mixed reactions. Newton turned scouts' heads when he ran the 40 yard dash in 4.59 seconds, which tied Washington's Jake Locker for the third-fastest time among quarterbacks, tied for the best broad jump at 10 feet, 6 inches and had a 35-inch vertical jump.
