The Blue Jackets went through the Washington Capitals like they were the Washington Generals last night. It was a 5-1 win before 14,121 at Nationwide Arena, and it was the easiest win so far on the Jackets’ five-game winning streak.

Here’s a subtle way to measure how well the Blue Jackets are playing right now:

They were certainly aware of Capitals star Alex Ovechkin — the NHL’s leading scorer — whenever he was on the ice, but coach Todd Richards did not fret over which of his forward lines was out there to check Ovechkin’s line. Matchups have become the other coach’s concern.

“As a coach, you don’t have to worry about matchups if everybody is responsible,” Richards said, beaming.

Cam Atkinson scored his 14th and 15th goals of the season. He skates on the third line with Matt Calvert and Brandon Dubinsky. Or is that the first line? Ryan Johansen had a goal, his 18th of the season, and an assist. He skates on the No. 2 line with R.J. Umberger and Nick Foligno. Or is that the No. 1 line?

Defenseman James Wisniewski and fourth-liner Mark Letestu also scored for the Blue Jackets, and goaltender Sergei Bobrovsky had 26 saves for his sixth consecutive win.

“Maybe in the past we were too worried about who’s on the ice and who we’re playing against,” Atkinson said. “Now we’re worried about our own game, playing hard. You have to be aware of the Ovechkins and the (Nicklas) Backstroms, but we’re just playing our game and good things are happening.”

The Blue Jackets led 3-0 early in the second period, chasing Capitals goaltender Philipp Grubauer after Johansen scored off a brilliant rush with R.J. Umberger at 1:44. Washington pushed back a little in the second period, but the Blue Jackets scored twice early in the third — a power-play goal by Letestu and a goal scored just after a power play expired by Atkinson — to push the lead to 5-1.

“Those two goals were great,” Richards said, “because you could see as soon as that went in (Atkinson’s goal at 4:24), it was just about running the clock.”

Last season, during that 19-5-5 tear to the end of the season, the Blue Jackets relied on Johansen’s line — no matter his wings — to play a checking role. That has fallen on the top three lines recently.
