While he did not delve into the nitty-gritty of any negotiations, Bruins general manager Peter Chiarelli did say during a conference call yesterday he wants to re-sign pending unrestricted free agent Jarome Iginla. As the period when other teams can talk to the Bruins’ UFAs approaches (teams can talk with those players beginning tomorrow, but formal offers must wait until July 1), Chiarelli allowed for the possibility he won’t be able to re-sign the winger and future Hall of Famer. That’s just one bit of business on Chiarelli’s plate as he heads to Philadelphia for the NHL draft later this week, followed by the free agency period. He still has to re-sign restricted free agents (forward Reilly Smith and defenseman Torey Krug), hire an assistant general manager, and hire an assistant coach. And if he’s able to sign Iginla, he may have to unload some salary. He said he has different scenarios on how to proceed with his team this offseason, and whether he re-signs Iginla certainly will affect the direction he goes. Choosing not to re-sign veteran forward Shawn Thornton was just the first of several difficult decisions facing Chiarelli, and they may not end soon. “There will be hard choices, but it may be that we don’t make hard choices and we keep as many people as we can and we go into the year and maybe we do make those hard choices as the year progresses,” said Chiarelli. “It may be that all these things happen at training camp, it may be that all these things happen in November. . . . I think a lot of people think that these hard choices get made July 1. Choices do get made July 1, it may be that we can’t sign Jarome, it may be that we go in a different direction, it may be that we can’t sign Player X or Player Y.
