While the world is in self-quarantine, Boston Bruins' general manager Don�Sweeney has been getting busy.� Sweeney has already signed 2017 4th round pick <a href=breaking-bruins-sign-goalie-prospect/>Jeremy Swayman</a> and 2019 1st round pick <a href=breaking-johnny-beecher-has-made-his-decision-wher/>Johnny Beecher</a>.� Now Sweeney has dipped into the free agent market and snatched up arguably the top available NCAA free agent.� NHL insider Elliotte Friedman reports that the Bruins have signed Jack Ahcan from St. Cloud St.� The 22 year old defenseman had seven goals and 18 assists last year in 33 games. Ahcan was never drafted despite playing for Team USA at the 2017 World Juniors.� <div align='center'><blockquote class='twitter-tweet' data-lang='en'><a href='https://twitter.com/FriedgeHNIC/status/1243292562733117444'> </a></blockquote></div>
