I don’t remember the last time a blue chip prospect that is on track to make the team within 1 season is traded for anyone at TDL. Owen tippet and even then it was just Tipper for Giroux + a bunch of stuff
To be clear I think it will probably be considered but I don't think Calgary will make Anderson available. Whether or not one considers it smart they're trying to ice a competitive team and should be looking to extend him in the summer. But no blue chip prospects don't get traded for deadline rentals, but kind of the point I'm making is an Anderson deal while hypothetically would occur at the deadline for cap reasons would be more of a hockey trade than a deadline rental.
If Calgary were inclined to sell him and rebuild it's a deal that cap allowing for maximum value could be made any time between the 2024 draft and the 2025 trade deadline. Once the latter is crossed, then there's a short window for Calgary to try and get better value by an early season 'sign and trade', which if they miss it comes down to a trade deadline deal and at that point they're getting the regular deadline assets - late 1st and later draft picks & second tier prospects, or nothing at all.
You won't find deadline deals but if you expand the trade of 1st line/top pair players with 2 years left to the draft then you'll find trade examples. My hockey mind tends to be stuck in the 2000's so the one that immediately springs to mind is Pavol Demitra for Patrick O'Sullivan - just scored like 90 points in his rookie AHL year, and the 17th overall pick.
