Putting Brandon Saad on the first line would push Pavel Buchnevich down to the second, a move forward Brayden Schenn thinks could provide some new energy.
"The past three or four games, my line and Thommer's line haven't been consistent enough," Schenn said. "So by shaking things up, hopefully it gives all of us a chance to get it going a little bit. It's a chance for myself to get it going and hopefully develop a little chemistry with Jake and Buchy."
With Jake Neighbours skating on the second line, he will continue to be relied upon to create offense.

The new lines will face a skilled Nashville Predators team Thursday night, as the Blues look to add another two points to their win total.
