I can see the Kings splitting the time for Wenyen and Williams in the big league club to cover about a 90 day span. That takes us close to the February trade deadline.
I think Vlade will try to trade the Vets; ZBo, KK, Ben, Shump to some salary dump team or as a third team to help facilitate a trade to get a pick or assets back by the trade deadline. Vlade may need their contracts to help facilitate a trade, no need to dump it now when we can manage two 2-way contracts to take us to the trade deadline.
If the Kings can't include the Vets contracts in a trade by the trade deadline, I think he has probably already promised them he would release them, so they can join another team in time for the playoffs. That's the way Vlade likes to work.
I think if Wenyen and Troy Williams show well, the Kings will guarantee their big league contracts after they release the Vets, after the trade deadline.
