Boston swept the Penguins in the Eastern Conference finals, but the Bruins will have a much different look next season than they did last month when they lost to Chicago in the Stanley Cup finals.
Nathan Horton signed with the Columbus Blue Jackets on Friday, and Tyler Seguin and Rich Peverley were traded to the Dallas Stars on Thursday.
Knowing he was losing Horton and not expecting Jaromir Jagr to return to Boston, Bruins general manager Peter Chiarelli said it was his goal to "reconstruct" the right side of his forward lines. Loui Eriksson was acquired in the deal with the Stars, and adding Iginla was the next step.
Iginla's contract is cap-friendly, counting just $1.8 million next season. If he achieves any or all of the performance bonuses, that will count against the 2014-15 cap.
