T-Mac or possibly Walker. Almost everyone else is a trade down, IMO, although you say that is off the table.
If you aren't mentioning Sanders being off the table, I would fail to see why a trade down isn't possible, however.
I don't think the argument is about the book value but about the player and the overall strength of this draft seeming to be short on elite talent. Add the fact that we have a ton of roster holes and that explains why a lot of us are against it.
