Chiarelli was hired by the B's on May 26, 2006, though he wasn't on the job until July because the Senators wanted him to finish out his contract with them.
The players below all played in the 2010-11 playoffs for the Bruins.
Already in the Bruins organization prior to Chiarelli's arrival:
1. Patrice Bergeron
2. David Krejci
3. Tim Thomas
Brought in by Chiarelli:
1. Johnny Boychuk - acquired in 2008 from COL for Matt Hendricks
2. Gregory Campbell - acquired in 2010 with Horton from FLA for Dennis Wideman, 1st-Rd, & 3rd-RD
3. Andrew Ference - acquired in 2007 with Chuck Kobasew from CGY for Wayne Primeau & Brad Stuart
4. Shane Hnidy - 2011 UFA signing
5. Nathan Horton - acquired in 2010 with Campbell from FLA for Dennis Wideman, 1st-Rd, & 3rd-RD

14. Dennis Seidenberg - acquired in 2010 with Matt Bartkowski from FLA for Craig Weller, Byron Bitz, & 2nd-RD
15. Shawn Thornton - 2007 UFA signing
Not listed are Zdeno Chara (2006 UFA signing), Milan Lucic (2006 draft), Brad Marchand (2006 draft), Tuukka Rask (acquired June 24, 2006 from TOR for Andrew Raycroft), and Marc Savard (2006 UFA signing, though injured for the playoffs), because they were all acquired after Chiarelli was hired but before he was officially on the job. Hard to say how much input he had with those (I remember there being controversy over the Chara signing because both he and Chiarelli had been in the Ottawa organization), but just to be safe I'll omit them.
