The Montreal Canadiens added a late seventh round pick at the last second during the 2017 NHL Draft. They shipped their 2018 seventh round pick to the Philadelphia Flyers in exchange for a late pick in the 2017 draft. They were only slated to have one selection after the fourth round, so it made sense that they would want to add a bit more prospect capital at the time.
With the pick that they added at the last minute, the Habs selected Cayden Primeau. At that moment, he was best known for being the son of Keith Primeau who had an excellent career with the Detroit Red Wings, Hartford Whalers, Carolina Hurricanes and Philadelphia Flyers.
