If the Flames wish to re-tool with younger players, and especially if they end up trading Hanifin, then the left shot Chychrun would be a perfect add at 25 years old, if he agrees to Calgary. Joseph was typically labelled as a cap dump before the season began and even after his decent start. I'm not sure how the Sens feel about him, but Calgary would add a guy who can play the right side just like Dube can. If he keeps putting up decent numbers, he would be a good trade candidate in a year or two when the cap is even higher.
Hanifin - Andersson
Chychrun - Tanev
Solovyov/Gilbert/Oesterle/DeSimone
The Senators fill a need for a competent, top right shooting D. If Weegar accepts the move, the Senators have him under contract for a while, and he, Chabot and Sanderson would comprise the core of their D. Kleven is there too. Dube is an RFA after this season, and with his numbers, is a total reclamation. Maybe he can resurrect a career in Ottawa, for sure I wouldn't pay him $2.3m again, so he'd be cheaper, or can be let go if they simply don't want to qualify him. Either way, they get their right D.
Sanderson - Weegar
Chabot - Zub
Brannstrom/Kleven - Hamonic/Bernard-Docker
