The NFL has never been known for having many signature athletes. It’s not a league like the NBA, where players are free from helmets and shoulder pads. As seen with Michael Jordan’s sneaker empire, the NBA has always encouraged individualism and building personal brands. The NFL has had a tougher time on that front.
To be a signature sneaker star in the NFL, there needs to be an universal appeal a player brings to sell shoes. Think a two-sport phenom like Bo Jackson, a charismatic showman like Deion Sanders, a human highlight film in Michel Vick or even an underdog who crossed over into fashion like Victor Cruz.
