I guess I can get it a LITTLE bit as you don't want things getting chippy and leading to bigger problems later. Ref was prob trying to nip any/all "extracurriculars" in the bud. That said, he could have just stopped play, huddled the players and said, "fellas, we're not gonna deal with this bullshit. anything else like that, ANYTHING, will earn you a T, and think about how that'll feel if you foul out later or if your team ends up losing by 1".
