Warning: Spoilers ahead for American Sports Story: Aaron Hernandez episode 5, “The Man.”American Sports Story: Aaron Hernandez is far from a comedy, but the introduction of the show’s fictionalized version of the title character’s fellow tight end meant the bioseries had no choice but to alter course a little. Rob “Gronk” Gronkowski is one of many real NFL players to be portrayed in American Sports Story. The athlete’s fun-loving reputation needed to be authentically put across, or including the character would have been a little pointless. While he doesn’t have a huge role in the American Sports Story season 1 cast, the actor who plays him certainly makes an impact.
