20. Zac Rinaldo
Rinaldo, acquired in a trade with the Philadelphia Flyers this offseason, will be limited to a fourth line role. He may need to step up as an enforcer with the departure of Milan Lucic, though this remains the Boston Bruins most puzzling offseason move. In four NHL seasons Rinaldo has just 8 goals and 16 assists in 223 games. His most significant impact comes in penalty minutes, where he has amassed 572 minutes in the box.
