Retiring is the worst option of everything because of salary cap rules would cause a cap penalty in Franzen case.
Best solution is to keep Mule on the books, but never ice him again. And let that contract die that way. We can use LTIR space to bolster the roster against the cap better, than with a recapture penalty if he officially retires.
He won't retire, we don't need to be worried about that particular angle in my opinon.
Good news for Franzen too is they can probably set him up with a job doing something, what with the terrible precedent the league has set in terms of Pronger. I never got the feeling he was going directly back to Sweden anyway, in terms of a lot of his interviews.
If he wants to play hockey again I wish him luck, but I will hold my breathe while he does it. I have always been a big fan of Mule, I just hope whatever he decides he has his long-term health. I don't think he has actually really thought that hard about the retirement angle or the pseudo-retirement, he talks about the kid part but also states he keeps waiting for the day he will wake up and it will go away and thinks if they made a deep run and his symptoms did go away in the next couple weeks he might be able to make it work. Doesn't seem at all like a guy willing to give it up right now.
I did think it was telling a while back that Ericsson said he hoped he would sit out the rest of the year... The guys know how bad this is, I am curious if some of his teammates will tell him to hang it up. You rarely see somebody as forthcoming as Ericsson was when talking about Mule a little over a month ago. There is obvious concern for him in that dressing room in terms of what his future holds and it goes well beyond hockey.
