In my opinion I would rank these deals 1. Vegas, 2. Dallas, 3. Colorado, with the Avs offer not appealing to me right now. I think the Vegas one is the only one super likely to happen, at least in some form, but the Dallas one is somewhat intriguing.
it would be cool to have rants and marner on the right side but that is setting the rest of the roster up for failure. Colorado can't afford that and hope to have depth to win a cup
Things like math and salary cap aside: Avs simply have no interest in having two $10 million wingers. They want and need to spread out their cap more evenly than that.
