What's 300-pound NFL Pro Bowl defensive lineman Calais Campbell really like? According to his recent appearance on go90's Here's The Rub, he's just a normal guy who likes J. Cole, boxing and The Matrix

In another hilarious interview, Nikolai Popov, played by comedian Andrew Santino, asks Campbell about his favorite movies, songs and of course, his shoe size. Of course it wouldn't be a Popov interview if Conor McGregor, who recently "fought" Game of Thrones star. If you're into Popov's awkward interview style, check out more episodes of Here's The Rub, featuring stars like The Mountain, Skylar Diggins and P-Rod.
