A lot of fan chatter (so take it for what it’s worth, which is nothing) that Theodore is the guy who’d garner the best return and free up the most cap space at the same time.
It's not impossible. I'd guess they'd want a top 6 winger like Buchnevich, Necas or Schmaltz coming back.
They have 6 legit NHL defensemen under contract. For a total of $30 million. (To compare, we have 5 mostly worse guys under contract for $27 million.) I bet Vegas will run with what they have. Someone will play his off hand. If they need offense they will add a couple of cheap guys chasing Cups or make late season trades like they always do. Who are you offering for Hague? The guys they would want (Marchenko,etc) are all RFA and Vegas would want cost certainty.
I didn't say they are absolutely going to trade Hague. I think he's more likely to get dealt than Whitecloud though.
Columbus' blue line is overpaid, so it's not really a fair comparison. But anyway, if I had to guess, I'd say Vegas are probably going to run Pietrangelo, Whitecloud and Korczak on the right side and Hanifin, Theodore and McNabb on the left. But that's just what I'm guessing. I don't know.
Vegas will not get a Marchenko-type player for Hague. That would be an overpay. They have an abundance of quality LD but not much in terms of quality bottom 6 forwards. As I said above, I've seen Texier for Hague suggested on CapFriendly. That seems reasonable. I don't see him getting a higher salary than Hague already has.
