Vikings rookie Jaleel Johnson donned a Sprayground backpack as he signed autographs for fans on the opening day of training camp. The Sprayground brand has become popular with NFL players, featuring designs from Pittsburg Steelers' Antonio Brown and New Giants' Odell Beckham Jr. “I heard about it actually a while ago because my roommate from college with the Colts has one,” Johnson said.
