The Kings are NOT going to trade either Turcotte or Villardi. The prospect of having a Center depth of Byfield - Turcotte - Vilardi, with all three able to slot in for each other, all being close in age, is not something that this team should trade away. It's rare that a team can draft that kind of Center depth so close together, Blake would be F'n nuts to trade that.
Other than that, the Kings are too early in their rebuild to start gutting the top end of their depth. They aren't going to be ready to contend for at least a couple years. When they get to the point where they are player or two away from getting to the next level, that will be when they start making trades.
