LeBron James, in the midst of an extended effort to revive his pre-The Decision, fan-friendly image, stars in a new spot for Sheets Brand Energy Strips in which he laughs, jokes and shows off his sparkling smile. The 30-second spot is the anchor for a broader marketing campaign in which consumers are directed to a Facebook page to create their own Sheets commercial. According to the company, the winning commercial will be aired on national TV and in movie theaters nationwide in 2012.
