Dlew, I couldn't disagree with you more on this point. Love when guys do something awesome and then act like they expected it to happen. Really, really good teams in all sports do this. Regular teams celebrate every stupid little thing. I loved seeing this reaction.
Sometimes they get really happy and wild when they get a takeaway. If their deal is "we're going to pretend not to be happy" when they get a TO, that's one thing, but be consistent.
