I think it's a little symbolic as well - that "turning the page" or "starting the next chapter" type of thing with everything that's been going on. While they've stepped in a large pile of shit, I do want to see the organization begin the climb back to normalcy. Not that Toews or Kane had anything to do with anything but this would be one of the final moves to really "start fresh". That said, it gives both another chance to compete which I'm sure they would appreciate.
Not sure what Patty Kane to the Penguins would look like but man alive would I love that.
