The big question is if they can afford him and that will be dependent on what Iginla is looking for.
The Bruins got him under the cap in 2013-14 by signing him to a contract that included a low base salary, but plenty of bonuses. Per the current CBA, it’s permitted for a team to exceed the cap ceiling due to bonuses, but then the difference gets charged to your following ceiling. In other words, part of Iginla’s contract from 2013-14 will eat into the team’s 2014-15 budget.
Boston could do the same thing again, but only if Iginla is willing to assume the risk of another bonus-laden, one-year deal. That might be a tough sell as he could certainly do better on the open market after scoring 30 goals and 61 points in 78 games.
That being said, the Bruins will reportedly be “very active” in the trade market and might be able to free up the cap space necessary to give Iginla a better deal.
