When the Los Angeles Kings traded defenseman Jake Muzzin to the Toronto Maple Leafs on Monday evening they took an important step toward doing something that was probably a year or two overdue — turning the page on their past glory and starting to finally look toward the future.

It’s time. It’s beyond time. Waiting any longer would have put this team in an even deeper hole that would have taken even longer to get out of.

Since winning their second Stanley Cup in 2014 the Kings have been stuck in neutral in the NHL’s worst possible place — the middle ground — somewhere between a contender and a lottery team, desperately trying to squeeze out whatever is left of an aging core by adding more aging pieces to it (Dion Phaneuf, Ilya Kovalchuk, Carl Hagelin, etc).

Yes, they made the playoffs twice since that last championship.

They also managed to win only a single game in those two appearances, losing in five games to a Sharks team that went on to win the Western Conference in 2016, then getting swept by the Vegas Golden Knights a year ago in a series that wasn’t anywhere near as close as the scoreboard. The two teams were playing a different sport for the four games, and while the Kings didn’t give up much, they never even seemed like they were close to scoring or were capable of doing anything to make Marc-Andre Fleury sweat even a little bit.

In between those two emphatic first-round exits were two non-playoff seasons. More than halfway through the 2018-19 season they are tumbling toward another spring that will be spent at home.

Big picture, this has been an alarmingly mediocre team for going on five years now. Since the start of the 2014-15 season the Kings are 17th in regular season wins, which is about as middle of the pack as a team can get.

The only two teams with fewer than the one postseason win the Kings have during that stretch are the Arizona Coyotes and Buffalo Sabres, and they only reason they have won fewer is because they haven’t actually made the playoffs.

It has become increasingly clear that there is a sizable gap between the Kings roster and the way it plays and the way the rest of the NHL is built. That gap is only widening, and the only way it’s going to get fixed is if management makes the painful decision to take a blowtorch to the roster.

Trading the 29-year-old Muzzin and his remaining contract ($4 million per year through the end of next season) is a start.

It can not be the end, and based on what general manager Rob Blake said after the trade it likely will not be.

“I don’t want to get into specifics of players, but we are actively looking at making moves for the future of the organization, yes,” said Blake, via the Los Angeles Times, when asked about trading more veteran players.

Quite honestly, there probably isn’t a veteran player on the roster that should be untouchable. Given that the only two key unrestricted free agents they have are Hagelin and Nate Thompson it seems reasonable to conclude that big-name, core players are part of those discussions.

The Kings are in a pretty dire situation here where they are not only old (the third oldest team in the league), but they have those players signed to long-term contracts. Looking at their current roster they have nine players already over the age of 30, with six of them age 33 or older. Almost all of those players are signed for at least the next two seasons at pretty sizable salary cap hits.

Kovalchuk, 35, has two years remaining on his current deal that pays him more than $6 million per season. Jeff Carter and Dustin Brown, both in their age 34 seasons, are signed for three more seasons after this one at a combined salary cap hit of more than $11 million per season (though Carter’s contract significantly reduces in terms of actual dollars because it was so front-loaded when it was signed).

All of this is going to make a rebuild even more complicated because they don’t have a ton to trade.

It seems highly unlikely that Anze Kopitar or Drew Doughty would ever go anywhere, not only because of their importance to the franchise but also because of their contracts (both of which contain no-move clauses).

Dumping Brown, Phaneuf and probably Kovalchuk would probably require significant amounts of retained salary, or perhaps even giving up something of value to dump what is left of those salaries.

The real value is probably going to be in trading players like Tyler Toffoli and Alec Martinez.

At 26 years old Toffoli is actually one of the “young” players on the Kings’ roster, and even though he is having a down year is still at least capable of being a 20-goal, 45-point winger. He is not a foundational piece or someone you would ever center a rebuild around, but a contender would absolutely find value in him especially at his $4.6 million salary cap hit the next through the end of next season.

Martinez is in a similar position in that he is still very good and has an attractive contract. There is no reason to think he could not fetch the Kings a package similar to what the Kings received from Toronto for Muzzin. Or at least close to it.

Then there is the elephant in the room that is starting goalie Jonathan Quick.

Quick is another one of those cornerstone pieces, along with Kopitar and Doughty, that helped bring two Stanley Cups to Los Angeles, and Kings fans should be forever grateful for that. But he’s also a player whose perceived value has probably almost always exceeded his actual on-ice value. He’s been great at times, and in the brightest spotlight when all eyes were on him. And that matters. But he’s also been just average at a lot of other times, and that matters, too.

The former always overshadowed the latter, and that still may be the case today.

He is 33 years old, has four years remaining on his contract, and given all of that is probably closer to the end of his career than his peak years. Given the potential enormity of this overhaul, it would probably be in their best interest to see if they can find a taker for that contract right now because they’re not going to be in a position to win in the coming seasons.

It might be painful, but it also might be necessary.

The Kings have been mediocre long enough. Now it’s time to take a step or two back because it is the only way they can actually move forward as an organization.

Trading Muzzin, a popular core player that helped win championships and was still signed beyond this season, was a start. It can not be where they stop.
