He has the hits (Stitches, IKWYDLS, Life of the Party, Treat You Better, 2nd and 3rd singles from Illuminate), he has the personality, the vocal ability, the stage presence, charisma, guitar, looks and likability. I think he'd put on a great show. He could invite Camila to sing IKWYDLS with him and then have 5H as a special guest to perform a mashup of Work From Home and Worth It while he dances in the background. I know Super Bowl usually has bigger stars like Madonna and Beyoncé but it wasn't always like that, they used to have marching bands and stuff. Shawn would definitely attract a younger audience too.
