I think Salvador may very well be off the books, or at least on LTIR, this year. I don't see him sticking when he's redundant and there are much cheaper options.
I don't know what will happen with Brodeur beyond this year. I'm not really worried though, post lockout it's been proven time and again that you do not need an all world goalie anymore to win the Stanley Cup. Whether Marty decides to go year to year with 1 year contracts, which is all he should do at that age or decides to retire we'll be fine at the position whether we need to sign someone capable via free agency, trade for someone or wait for a prospect to be ready.
Personally it'll be a lot harder to see Marty finally hang them up than it will be for the team going forward.
