A bit of an overreaction, I doubt Playstation is the reason the Steelers are losing, but according to ESPN, Tomlin has banned all games (pool, ping-pong, cards, video games and etc) from the locker room.
I have to confirm if air hockey was also banned, if so, then Tomlin must be fired, it isn’t American to ban air hockey.
I am sure they will find a way to blame GTA V for this.
