Here are the first few paragraphs of Sunday’s game story:

One of these days, the Kings won’t be able to rely on only three players to score in order to win. One of these games, Jeff Carter, Tanner Pearson and Tyler Toffoli won’t be able to continue to work their magic. Sooner or later, an opposing team will shut them down.

It’s bound to happen eventually, right?

Perhaps, but certainly not during the Kings’ 5-2 victory Sunday afternoon over the Columbus Blue Jackets at Staples Center. Pearson scored two goals in the third period, Toffoli added one goal and three assists and Carter recorded a goal and two assists. Overall, That 70s Line has combined to score 16 of the Kings’ 21 goals in the run of play.

Here are three things about the Kings’ sixth consecutive victory:

First, center Anze Kopitar suffered an unspecified upper-body injury after a collision behind the net in the second period and could not return to the game. How serious it is remains to be seen. Here’s what Kings coach Darryl Sutter said: “He’s all right,” Sutter then had the same response when a reporter asked if Kopitar could make the Kings’ five-game trip, which begins Tuesday in Philadelphia.

Second, the Kings’ depth is sure to be put to the test sooner rather than later, especially if Kopitar is sidelined for any length of time. Or if he’s at something less than 100 percent for an extended period. Marian Gaborik and Trevor Lewis are each sidelined by upper-body injuries and not expected to play soon. Defenseman Slava Voynov continues to serve an indefinite suspension by the NHL after his arrest last week on domestic violence charges. Salary-cap issues mean the Kings can’t recall a player from their AHL team in Manchester N.H.

Third, Dwight King’s second-period goal gave the Kings a fourth player to score this season. Tanner Pearson has seven goals, Jeff Carter has five and Tyler Toffoli four, Kopitar has two and King, Dustin Brown and Justin Williams have won each. That 70s Line, as Pearson, Carter and Toffoli are known, has accounted for 16 of the Kings’ 21 goals in the run of play this season. It’s an amazing run by a talented line, but it’s also potentially damaging since they’re bound to cool off eventually and others simply have to step up and contribute more to the bottom line.
