Grzelcyk is not the only one who will be trying to make one last impression on the Bruins' decision makers Saturday night. Much of the roster for the game consists of players trying to secure a place on the varsity.
"There's still a few guys where we want to get a little bit of a read on, if some guys jump off the page a little bit for future call-ups," said Cassidy. "Everyone is in a different spot. There are some guys that are in the lineup that need to sharpen up their games. As a team you want to continue to build on your identity and be hard to play against, make sure we're playing with pace and executing the things we're asking."
One player who is not expected to suit up against the Blackhawks is rookie winger Anders Bjork, who Cassidy said has all but sewn up a spot.
"Bjork looks like he'll start in the lineup. I don't want to say concrete…looks like he's going to be a fit," said Cassidy. "We've used him with [Patrice Bergeron] and [Brad Marchand], but he can play the other side. So could he flip with [David] Krejci and [David Pastrnak] as well? We haven't looked at that much, but it could happen.
"But we like where his game is at right now. We just think that Bjork is probably the furthest ahead of all the young guys."
Right behind Bjork are fellow youngters Jake DeBrusk and Sean Kuraly, both of whom will also be trying to make a final push against the Blackhawks.
"DeBrusk we're going to keep in there. We're looking for a few more things out of his game ¬- we like it as well," said Cassidy. "We're putting Kuraly back in there, but we like where his game has been and what he brings, energy and turning pucks over. Hasn't resulted in a lot of offense, but we believe it will over time if he continues to play like that.
"We're looking at him on the wing a little more tonight - we've had him at center - because he might have to move around."
