This season, there are two candidates, Lane Hutson and David Reinbacher. In the case of the American, it all depends on whether he prefers to continue his studies. As for the Austrian, he could very well come to North America and play for the Canadiens.
His regular season in Switzerland ends on March 4, and unless there's a surprise, his team is not expected to make the playoffs. He could be the next young player to finish the season with the Canadiens.
With 20 games remaining for the Canadiens after Reinbacher's season with Kloten, it provides ample time for the young man to acclimate to North American hockey and also gives the team a good idea of his development.
