Sure, if you believe Mac isn't open to moving any of those guys then okay. But I disagree. Ovie's obviously not getting traded, and I think 19 is untouchable per Ted, but that's probably it for the absolute keepers. Doesn't mean all or even any of the rest get moved, but I think Mac is open to it.
I'd say Kuzy is the best option for a trade because he's a total waste of space but has such a tantalizing skillset. Carlson is tough to move before he's even returned from injury, so maybe he's on the block in season next year. Oshie... that probably hurts the room, but it's not out of the question.
Mantha hopefully goes, and I am not in the camp that thinks he's a giveaway. He's still under 30 and is only signed for 1 more season. Some GM could take a chance on a rebound year.
So tl;dr: I think Mac has a plan and is pursuing it and has already demonstrated that he's willing to move guys.
