John Cena threatens to dribble LeBron's face "like a Spalding ball"

John Cena has been known to make threats in the ring, but now he's trying to goad "Trainwreck" co-star LeBron James into the ring —- or at least that's how it sounds. I don't know what's worse about this threat —- his calmness or his awful attempt at basketball humor. Either way, I don't think LeBron James is getting into a ring anytime soon to settle some made up score.
