looking at this, it looks like it is all cap issues. They have a ton of dough tied up in mediocre D and some guys like Kucherov, Namestnikov, Killorn and others for a total of 7 RFA's on the roster and those 3 are good part of their team. There isn't enough to go around. You could probably keep 2 of those RFA's long term and get a nice package for him. He is elite and you should find a way but the numbers don't look good.
Then both goalies come up the year after. Enjoy Toronto Stammer.
