As NHL free agency approaches, teams are getting ready to strengthen their rosters. The Boston Bruins have a lot of<h2>key restricted free agents</h2> to address. <h2>Trent Frederic</h2> had an impressive season with 17 goals and 31 points, seeking a raise from his $1 million contract. Goalie <h2>Jeremy Swayman</h2> showed promise with a 2.27 GAA and .920 SV% and deserves a significant raise from his $925,000 salary. The Bruins also have key unrestricted free agents to consider. <h2>Patrice Bergeron</h2> and <h2>David Krejci</h2> are both contemplating retirement. <h2>Tyler Bertuzzi</h2>, acquired at the trade deadline, aims for a substantial contract after his strong performances. <h2>Nick Foligno's</h2> two-year contract may have been overpaid, but he helped with experience and his gritty style of play.
