FOCUSING ON CAM: The football season may have ended, but there’s no real off-season for professional athletes. And so tonight, Under Armour will unveil its newest football commercial, “Cam’s Night Out,” on the NFL Network during the NFL Combine in Indianapolis. The 60-second spot depicts a Friday night in the life of Carolina Panthers quarterback and 2012 Rookie of the Year Cam Newton. But instead of a dance club, Newton spends his night on the field, throwing passes, blocking and working on technique drills. Newton’s musical accompaniment is provided by producer AraabMuzik, pictured on a drum machine in the broadcast booth above the field, and his apparel of choice is Under Armour’s Baselayer and Highlight Cleats, which will debut on April 6.
