I agree with Marc Dumont:
"I’ll keep this short and bitter: the second line is terrible and it’s beyond time St-Louis addresses the situation. There’s no chemistry, and all three players clash when it comes to their style of play.
As for the potential solutions, if Harvey-Pinard is out of action for any length of time, it may be time to give Juraj Slafkovsky an audition on the top line. There’s really nothing to lose by giving him a chance to play with some of the team’s best players, and there’s a lot to gain by removing him from the second line, which has been detrimental to his development. If the Canadiens cannot afford a top-line audition for their first overall pick, the AHL is the only destination that makes sense. I wouldn’t go as far as saying he’s costing the team wins, but it’s clear that the NHL is not the right league for Slafkovsky at the moment, at least not in his current situation. He’s not having fun out there, and it shows. Once a player starts overthinking every single pass and shot, things only get worse. It doesn’t matter what people will say about the AHL assignment, either. Yes, there will be some (justified) criticism around the league, not to mention a bevy of jokes made at the team’s expense, but it’s a small price to pay when it comes to the development of such an important player."
