The Kings are playing a style which should produce more goals. So far they haven't played any teams in preseason capable of exposing the Kings defense.
I doubt this team wants to get into "fast break" games against Edmonton, Calgary, or Anaheim. Then factor in teams like Chicago, St. Louis, and Dallas which can also play the "run and gun" style much better than the Kings and I don't think it's a style the Kings can play against every team.
If they are going to change the identity of the team, it will take some time to get the personnel to make it work. The games likely will be higher scoring and perhaps more exciting, but I don't expect a big payoff in the standings.
