Melton seems like quite a project. Not sure he gets any minutes on this team.
I wouldn't expect the player they take at 27 to have any impact whatsoever during the upcoming season. This will be a draft-and-stash international player, or a developmental college player with lots of upside (who will play in the G-League to start his career).
The only way I see it playing out any differently would be if somebody unexpected falls to 27 or if Danny trades 27.
