I doubt this will happen. Lavi didn't want Jagr resigning in Philly years ago.
Have to see what happens with Fisher first, at least.
1 - Johansen
2 - Forsberg
3 - Arvidsson
4 - Bonino
5 - Jarnkrok
6 - Smith
7 - Fiala
8 - Hartnell
9 - Aberg
10 - Sissons
11 - Watson
12 - Salomaki
13 - McLeod
14 - Gaudreau
There is basically one spot available if you sent Gaudreau down. I'd keep that for Fisher for now. If Fisher retires, it could be an option to look at one of the leftover UFAs, but I think a lot of them are players who don't have much speed left, Jagr especially, and I'd probably rather continue to promote a speed game than take on slower veterans.
That said, when you have the cap space and at least a potential roster spot, it's basically a free asset, which could provide flexibility in some capacity down the road. *IF* Fisher isn't coming back.
