NHL free agency opened Saturday at noon, and the Florida Panthers wasted no time making moves. They quickly filled a need on defense with the signings of Oliver Ekman-Larsson, Mike Reilly, Dimitri Kulikov and Niko Mikkola. Kevin Stenlund was brought in as a depth forward and Grigori Denisenko resigned, while Radko Gudas, Givani Smith and Alex Lyon have signed deals elsewhere.
