The moves made Monday were necessary to retain negotiating rights to the restricted free agents. Granlund was second on the team with 26 goals this season, and Niederreiter was third with 25 goals. They're both candidates for a long-term contract.
Defenseman Christian Folin, who had eight points in 51 games with a plus-10 rating, did not receive an offer. He'll be an unrestricted free agent but can still re-sign with the team.
