This summer, after winning back-to-back Stanley Cups, the Florida Panthers were able to re-sign Brad Marchand, Sam Bennett, and Aaron Ekblad.
Ten years ago, after winning their third Stanley Cup in six seasons, the Chicago Blackhawks dealt away Brandon Saad, Patrick Sharp, Kris Versteeg, and Antti Raanta through trades and lost Brad Richards, Antoine Vermette, and Johnny Oduya in free agency.
That is a lengthy group of the roster to lose in free agency. Part of the reason for the loss has to be because of the flat cap the NHL faced. From 2014-15 to 2015-16 the NHL salary cap went from 69 million to 71.
