Why so impatient? There aren't any realistic targets out there that are going to add 5-10 wins to the Kings. They are still developing all the young guys. Instead of concentrating on wins and losses, it's better to concentrate on player development.
Will Buddy put up over 15ppg? Can Bogs put up 15ppg after finally getting a rest? Will Bagley be a double double machine? Will Giles show flashes of the player he once was? Will JJ start knocking down his shots? Will Fox improve his shot and play making abilities? Will Skal become a useful stretch 4 type player? Can Frank Mason cement a place in the league and finish at the rim more consistently?
There is a ton of stuff that needs to happen before the Kings can start winning. They could get a veteran PG and SF and start a bunch of old guys and possibly get 33 wins or so but what's the point in that? I think most Kings fans are aware enough to realize that if these young players don't go, the Kings don't go. If they can't improve with this core then it really doesn't matter who they sign because it'll be a failure either way.
