They have carried the safety issue too far and it now damages the flow of play on TV. They call a penalty when there is clearly no intent to harm the QB (often rewarding theatrics). Also.they need to revise the holding penalty. So many of those holding calls are for such short duration infractions that they really have minimal impact on the action yet, there we go stopping the action for another questionable flag. All this makes me think I saw the best football back in the 70's. Two hand touch anyone?
