I think there would be a market for Forsberg, but we may have to take back cap, and the return will be something like a 3rd to 7th round pick. If it's a hockey trade, we aren't getting Arvidsson. I think that we would get something like a bottom 6 forward or bottom pairing D.
I don't think it makes much sense to trade him because with Ullmark's up and down health, goalie depth is worth more to us than say a 4th round pick. If Forsberg was still playing like he was earlier in the season, then my opinion would be different.
There aren't a lot of goalies available, but look at what Wedgewood went for, a 6th round pick and a fringe NHL goalie for depth. That's probably Forsberg with retention would be worth. So I'm not sure I see the point unless we are out of the playoffs and sellers.
