There is not a case in the last 13 seasons where the franchise would have been successful if they had just stuck to their guns and kept any of the players. The reason why fans want other team's prospects is because our players suck for the most part and the fans know that the Kings literally cannot make the playoffs until a big group of our current players are gone and other team's players or prospects from the draft are brought in.
We know bad basketball better than any other fan base. So far, we haven't been wrong on any of our players. If we think they suck, they normally suck. If we think they're a bust, they're either a bust or at best a back end of the bench rotational player. Not once have us fans crapped all over a player and then had them go on to another team and be wildly successful.
If you want to hammer on something, hammer on the franchise for getting rid of two good coaches who have had the best track records in recent memory with the franchise. The fans wanting better players because our players suck isn't something to rag on them about because they're right about that.
