Fighting is already basically gone. .19 fights a game. The game has evolved. Scoring depth is mandatory, enforcers are gone.
Not completely. It is not like it used to be. But teams have to protect their stars from being targeted. Teams also have to retaliate for cheap shots on teammates. Take fighting out completely and guys like McDavid, Crosby, Ovechken,....., would probably have shorter careers. It is a game within a game. IMHO. Love Hockey. Go Pens.
