St Louis dangling Dunn and Tarasenko clearly have some opportunities available to them to navigate the expansion draft. I don't know what those are so I can't really say what their best course of action is but I'm guessing a 3rd and a mid level prospect for Dunn is not enough, as Dunn at least has value to them as expansion draft fodder.
Do we know who the selection would likely be if they traded Dunn?
