Not too often a team that just want a Stanley Cup has the prospect pool that the Bruins do.
They have to blue chip prospects in Tyler Seguin and Dougie Hamilton. Jordan Caron is NHL ready right now, as is Steven Kampfer and possibly Matt Bartkowski. Zach Hamill, Ryan Spooner and Jared Knight are all going to contend for an NHL roster spot this camp. Did I mention Yuri Alexandrov yet? And to add this on top of a team that has only 3 players over the age of 30 in Marc Savard, Tim Thomas and Zdeno Chara.
The Bruins could not make one move this offseason and still improve the team just based on experience. They have the team built now and for the future, which is very hard to do in the NHL salary cap era (see Chicago).
