"Listen, everybody likes the football their way. That's why I make sure our guys rub the balls down in a certain way - have them rub a couple balls down and make sure I like it - and once they have the ball the way I like it, I trust them to do that from that point forward."
Joe Flacco likes his balls a certain way. He has a whole team of people attending to his balls and rubbing them down to his exact specifications. Don't act like you wouldn't do the same thing if you were in his position.
