I fear the efforts will be mostly in vain and will be more parallel to an over-legislated, over-lawyered society. How about penalizing the donnybrooks, not the on field celebrations? If Player A winning a touchdown waves (non menacingly) at opposing Player B, make them kiss, hug, or shake hands in the middle of the field or something, but don’t screw up the scoring system.
As I wrote before, score the touchdown first. He was heading untouched into the end zone. Once you score the touchdown, than do all the dancing and parading around you want. You will most likely be penalized, but the score counts. You will probably get a 15 yard penalty assessed from the kickoff line. The TD stands. He just had to score first. Its so simple. That would have left the opposing team with perhaps good yardage, but the outcome could have been better.
