The Kings get off older players' expensive debt and go young. The Kings could acquire any of Mara, Lendenborg, or any of a number of skilled younger players. Moody has excellent all-around game, has a 7-foot wingspan at guard, and shoots lights out from 3. The Kings will need to eject some more older players, but this appears to be a road back.
As for GS, they lose a great pick, but risk it on 2 players that nobody else in the NBA wants at those costs and production. PS, if anyone locates Sabonis' distance shooting game in a Lost & Found... please return it to GS.
