Pittburgh wont trade him ,who really cares if they lose him in the expansion draft .They are trying to go for two in a row ,and him being in Pittsburgh helps try to accomplish this .That alone has value
I think that's what will happen, precisely for the reason you mention, and that they will just buy him out next summer (because of the NMC).
Personally, I would rather get
something for him before they have to dump him for nothing, but then again there are very solid reasons for keeping the same band back together as you look for a repeat, and especially in MAF's case, keeping a very popular locker room guy in the mix. I think if he knows its definitely the last year, he wont fuss or agitate but play his part and do what he can to help the team.
