“We’ve had that line play twice together and it’s been very effective. Paajarvi is back feeling good about himself now, so we put him in and keep him going. We want to keep that line together for as much as we can here, finish the season and see how we look.”

It represents an opportunity for Paajarvi, who has endured a fractured season after coming from Edmonton in the David Perron trade. Bothered by injuries at various times, Paajarvi has bounced in and out of the lineup, playing in 49 of 75 games.

But after he sat out the Dallas game Saturday, it appears Paajarvi will get an extended look as the Blues try caulking the hole created by the injury to 21-goal scorer Tarasenko. Paajarvi acknowledged the fluid nature of his status has been a challenge, but he’s eager for any opportunity.

“Of course, it helps when you’re on a line for weeks or months, or even days,” said the 22-year-old Paajarvi, who has six goals and six assists. “If you bounce around, it is hard to find the chemistry and to get something going. But you have to try and find it.

“You have to be professional about it, because it is going to change. Everybody changes over a season, some more than others. But you just have to be professional about, try to bring your game and see if it helps others on the ice.”
