Sharks have 0 interest in Ullmark with Reimer having a better season than him and Hill being already on the roster and showing signs of a turn around.
I'd rather have Ullmark over Hill but that's not really a feasible option. Ullmark has a full NMC through next season. Don't see why he'd leave when Boston will keep him there through this season with Rask and then probably need him with Swayman at least through next season. By the time Ullmark is probably actually available to the Sharks, Hill and Reimer's contracts will be expired. I could see the Sharks trading for him at that point but not before then.
