Corey Schneider was traded to the Devils for the 9th overall pick. That is probably a good comparable.
Marc-Andre Fleury was a straight up cap dump to Chicago so you can't really use him as a comparable.
Goalie market will vary on supply/demand. Demand for Schneider was higher with Edmonton and New Jersey; Schneider was also a little bit younger. Lately it just hasn't been a good time to be selling a goalie since most teams have a #1 (or somebody they're paying like a #1).

Pittsburgh, Carolina, Ottawa, Los Angeles, and San Jose might be the only teams looking for a starter and I doubt the Sharks would be looking at Ullmark. Pittsburgh's given up a bunch of picks, so maybe makes more sense for them to go the free agent route. Could see LA extending Korpisalo, but maybe there's a deal to be had there? Boston might prefer to deal Ullmark out of conference if given a choice. LA might have some extra ELC bodies that could aid Boston's cap crunch.
