HM: Kraskovsky, McKenzie, Tanev, Phillips, Lipon, Cederholm, Kostalek, Suess, Evingson, Holm, Stallard
Highest riser (from the previous list): Niku +12 (biggest jump by a skater on record)
Farthest faller: Lemieux/DeLeo -5
Graduating from that class are: 1. Connor, 2. Roslovic, 5. Poolman, and unranked Tanev. #12. Foley, was traded. Kostalek's gone to Europe. Stallard was not signed (and not drafted yesterday so he's a UFA). 16. De Leo, Phillips, Lipon and 6. Comrie are RFAs, so not sure about their statuses yet.
So at least 4 spots open up for someone.
