Regretfully, the bruins For an unexpected reason, five important players threaten to quit.

So what should Bruins General Manager Don Sweeney do with the extra money and resources? A top-six center is a clear need. A scoring winger would be a nice addition. But a sneaky hole to fill could be on left defense. Rookie Mason Lohrei came on strong in the postseason, and Hampus Lindholm is a minutes-eater. Parker Wotherspoon can play on the left side, but another defenseman could be necessary for depth purposes. Here are five options in free agency:

Martinez is up there in age but has been a stout defenseman who has won three Stanley Cups.

There has been speculation that Martinez would consider retirement due to injuries and age. However, on a short-term deal, Martinez could be a good get for Boston. The fourth-round draft pick in 2007 is a big-time shot blocker with 244 two seasons ago.
