He had 17 points, including 5 goals, in 31 games last year with the St. Louis Blues. Remember that he won the Stanley Cup with the St. Louis Blues in 2019.
As for Mathieu Perreault, he just spent the last seven seasons of his career with the Winnipeg Jets. At 33 years old, the Quebecer could decide to spend the last seasons of his career at home. Remember that he is a native of Drummondville. In the past, Perreault was a player capable of putting up a considerable amount of points, hence his five career seasons of 35 points or more. However, if he comes to Montreal, he would be limited to a secondary role, just like in Winnipeg.
