The last two players who would be happy by this would be Kopitar and Doughty. McLellan's defensive based systems have allowed them to retain their top spots on the team. If the Kings adopted a more offensive style you would quickly see those two struggling to remain key cogs on this team. Hell, Anze has struggled to keep up with the pace of the 1-3-1 at his advanced mileage.
We just saw a coach whose team was purring totally lose focus by two players who went into business for themselves instead of maintaining something that was working.
Now don't get me wrong, they were going to fold quickly in the playoffs again, and young players progress was clearly being thwarted in favor of immediate results. A new coach was necessary - just not for the reasons that ultimately got him fired.
