Buffalo Sabres sign defenseman to 7-year extension after just 54 career games

Samuelsson, 22, was selected in the second round (32nd overall) by the Sabres at the 2018 Entry Draft. Most of his NHL games came last season, as he appeared in 42 games with Buffalo, registering 10 assists. He also appeared in 22 games with the Rochester Americans of the AHL, collecting 2 goals and 13 assists.

According to Sportsnet's Chris Johnston, this isn't the first deal of this kind, as the Dallas Stars had a similar deal for a young John Klingberg:

Of course, that worked out well for the Stars, but time will tell for the Sabres.
