NFL Personal Fouls

There should be a distinction between fouls made during the course of the play - those that could alter the outcome - and fouls made after the play is over.  

A chop block or a face mask tackle could *alter the current play*

Taunting, late hits, excessive celebration, other "unsportsmanlike conduct"... well, those by definitoin do not alter the play.  They are not FOOTBALL violations, they are SOCIAL violations.

As social violations, they should have social penalties.  I propose that any "15 yard" variety of penalty that occurs outside of the normal play be dealt with by the equivalent of hockey's game misconduct.  The player is ejected and the matter is refered to the league.  I would also suggest that in football, such a penalty occuring in the 4th quarter also result in ejection from the first half of the next game (and in hockey, such a penalty in the 3rd period result in ejection from the 1st period of the next game).

Not only would this mean that a late hit doesn't give a team some ridiculous first down and swing the whole game, but it would mean you'd see far fewer of the violations.  After all, it is easy to justify 15 yards on a kickoff play... but could your team really win without you?  Most egos won't allow it.
