My best guess here is that they aren't announcing they are taking Murray because if they get a good offer then they don't want Josh Rosen knowing he wasn't the top option.
It really looks like it is:
Option #1 Trade Down for a bunch of assets
Option #2 Take Murray
The only way it won't make sense is if they take Bosa or Williams at #1.
