I said in the first post that the Blues pretty much want to go with Bergland, Backes and Schwartz down the middle. Schwartz is one of the most highly rated prospects in the NHL. McDonald has had concussion issues which lowers his value a lot. He's also 34 which lowers his value a lot. I really don't think the Blues have any issue dealing him for a 3rd. They want to go with Schwartz instead.
