Boston Bruins Draft Pick Retires At Age 23

The last name has been around the NHL for a few decades. Jamie Langenbrunner spent 18 years as a player, mainly with Dallas and New Jersey and has been in NHL front offices for more than a decade since he retired. But his son, Mason, a fifth-round pick of the Boston Bruins, has decided to retire at the age of 23.

Mason hadn't signed his ELC yet with Boston, and had until Aug. 15th to do so, or become an unrestricted free agent after spending four years playing on the blueline at Harvard. Instead, according to the Boston Globe's Kevin Paul Dupont, the younger Langenbrunner has decided that pro hockey isn't for him, and has retired from playing. He will be pursuing a business career with a protein bar start-up company among other pursuits.

"Mason opted to retire his skates while pursuing a business path as a partner in a couple of start-up companies," Dupont says.

The 6'3" d-man was the captain of the Harvard club this past season, though he was never a top-four option. Over his four years there, he registered a total of nine goals and 26 points in 130 games. 

The Bruins selected Mason in the fifth round of the 2020 NHL Draft. His dad had been an assistant GM in Boston at the time of that Draft, and in fact, for the past 11 years. Jamie recently moved to the Nashville Predators, where he'll be a special assistant to Chris MacFarland on his new front office team.
