The Boston Bruins hold a boatload of depth in their prospect systems despite top prospects such as Torey Krug and Dougie Hamilton graduating this season.

There are not too many significant changes to the Boston Bruins Spring Top 20. There were a couple notable graduations however, led by former number one prospect Dougie Hamilton.

The Boston Bruins have stockpiled prospects and the Providence Bruins are starting to see some of those players shine. Multiple prospects are starting to see time at the NHL too as the Bruins have dealt with the injury bug this season.

As the AHL season has entered full swing, so have the NHL recalls. Many AHL players have already seen considerable time in the NHL, or have spent a large number of days traveling between where their parent club is playing, and where their AHL team is located.

The Boston Bruins have only one prospect currently playing at the major junior level, and most of you have probably never heard of him. His name is Mitchell Dempsey.
