I think if you are worried now, at this stage of the game, then you just aren't looking at the big picture. Nothing is every the same as it is in the preseason, and that goes both ways.
The Kings are who they are; a mosaic of talents and characters. They are a team that features at least 3 All-star candidates in their starting 5, two other players that aren't too shabby themselves, the best stating guard not in a starting lineup and a mix of solid reserves and exuberant rookies to round out the bench. They can score with the best of them, put on a passing clinic and even play a little defense (when they want to). They are a team capable of winning. As a fan, that's all I can ask for.
I'm going have to steal a line from the folks on the Kings post game show and say that the Kings are just so easy to pick on. Pundits don't know what to make of them, so they put them down. Its crazy to think that this team won't be good and its even crazier to start searching for the panic button
....IMHO
Edit part II:
As far as a defense goes, I subscribe to the theory that defense is 90% effort, you have to want to play it. Right now, the team is just trying to get through the preseaon with out any injuries. I was a little miffed at the team for Friday nights game, but upon further review one has to realize what is going on.
This year, more than any other year I think Kings fans have to patient. Sit back, relax and eat some popcorn!
