This is correct. Many of us in Nashville didn't want to see Carrier re-signed at all, and were somewhat aghast when he got the $3.75M. The way we look at it, getting a reclamation prospect who may or may not ever become a regular player for us in Barron does indeed represent Cap dumping Carrier. Which we don't mind, because we had been wishing the team never signed him in the first place.
I don't think there is any huge hope pinned on Barron. We saw the team say nice things about Philip Myers and Cal Foote when they came along as reclamation projects in trades, but end of the day there was no salvaging them. Of course they are going to say nice things about a guy they trade for. If by some miracle they do salvage him, then of course Trotz will also say they knew all along. If - which is more likely - they don't salvage him, we'll all shrug and say it didn't hurt to try, but all along the real win was in dumping off a contract we didn't want.
I'm glad Carrier is doing well for the Habs, though. He always tried hard for the Preds, even if he couldn't seem to understand his role or stay on his feet. I don't think he's a top-4 defender on any team with a good defense corps, but he tries hard enough and has enough skill that he can fill in there while a team tries to find better options, which is basically what he has been doing for the last few years with the Preds. Eventually you need somebody better if you want to compete. The Preds were clearly hoping to sign somebody better on the UFA market last summer, but once they knew that they couldn't line up a proper RD upgrade on July 1st, they fell back on keeping Carrier around. The team is clearly planning to try again this coming July 1st, but realized that they're just as well off with a cheaper fallback like Blankenburg as they were wasting money on Carrier.
