There are likely third teams you can weave in to give up a pick for Williams/Kleber, but I'm keeping it at two for this.

Grant has been downright horrible, one of the worst players in the whole association, for about 2/3rds of the season now. This Mavericks roster badly needs a consistent third scorer, and here they get it in Bojan.

Some reliable big depth in Stewart, who has bene rumored in mavericks talk anyways and a more reliable backup point guard option in Morris.

Pistons add a pick, a swap, and potentially assets for more trades.
