The Mavs don't have any picks incoming, at least per this:

IMO, simply stripping them of pick 10 would be the harshest punishment (as opposed to letting it go to NYK this year). It would mean they tanked out of the playoffs for nothing, they'd still owe that pick to NYK for the next two seasons worth of lotto protection, and they'd be unable to trade away their 25 or 26 pick due to those protections. They already can't trade away their 28 pick because they traded their 29 pick, meaning the only have one tradeable FRP left to try and improve the roster. They might end up forced into a position where they have to move Luka for a haul in order to rebuild their team.
You hate to see it.
