Well, that's one domino that fell, and as far as trading Ryan goes, it wasn't a good one. No one in the Atlantic has loaded up yet, and the Penguins probably aren't a team that can make a play for Nash or Ryan. Semin's the next domino to drop I'm guessing, but if he doesn't go to one of those three, and Nash goes to Detroit, I have a feeling we'll take Ryan off the table.
Best case scenario, whether we trade him or not, Penguins somehow add one of them. Nash to the Rangers might force Philly to step it up, but a bidding war could also get us that best possible offer.
