Once one of the more feared lines in the NHL, the Jaden Schwartz-Brayden Schenn-Vladimir Tarasenko trio has run hot and cold since Tarasenko and Schwartz returned from lengthy injury-caused absences.

Lately, it’s been more cold than hot.

“I get it, it’s a results business and we need results from them,” coach Craig Berube said Friday, just before the team left for Arizona. “I think the work ethic’s there. I think they’re close to breaking out, I really do. I think if they keep getting chances like they are, they’re going to go in eventually.”

But the line wasn’t a factor Saturday in the Blues’ critical 3-2 loss to the Coyotes. Those players didn’t dent the scoresheet, registering no goals and no assists. And they combined for only four shots on goal.

Schenn is mired in a 16-game goal drought, the longest in his four seasons with the Blues. Schwartz had two goals in the Blues’ 9-1 rout of Minnesota on April 9, but those are his only goals in 14 games since returning from injury.

Tarasenko has played 19 games since returning from his latest shoulder surgery and has three goals and eight assists in those games. That’s about a 13-goal pace over a normal 82-game season, far below what the Blues are used to from someone who’s a perennial 30-goal scorer.
