Probably not good. The longer a player plays for the team the higher the cap recapture penalty I think. Capgeek had a calculator but since the website's been gone I can't find any other source to do the calculation
If injury is what prevents Kronwall from playing, they'll have him sit out his contract on LTIR rather than retire. Much like Franzen. If there is a cap recapture penalty involved, I'd imagine management would do whatever it takes to avoid it.
