W hile many were busy criticizing Cam Newton for wearing a towel on his head, they missed what was actually on the towel. The savvy product placement helped Newton land a Gatorade deal after his rookie season, and since then he’s gone from endorser to comic book superhero.Gatorade, in partnership with DC Comics, unveiled the Panthers’ quarterback as a character named The Blender in November. Now the sports drink giant has quietly started rolling out ‘League of Captains’ bottles that feature Newton, Broncos quarterback Peyton Manning, Redskins quarterback Robert Griffin III, and Texans defensive end J.J. Watt.Newton was featured on a limited edition Gatorade bottle in 2012, and it’s unclear how wide the new campaign will spread. Images of Newton’s ‘Blender’ bottle have been popping up online, with one already being sold for $14.99.
