There are things that happen on/off the court during a game that don't get caught by the cameras or in the game log. I watched him in person probably half-a-dozen times, and the one constant was that he wasn't always focused on the game. He didn't always hustle up the court, he didn't always reach for that board, etc. I know you can say that applies to a lot of players at various times, but it happened A LOT with WCS. He's the one who laid out his career plans when he got to the Kings. He said all the right things and the Kings universe embraced him with open arms. Unfortunately, as I said above, he didn't walk the walk. He stepped into DMC's shoes and fully expected to be as much as impact player as DeMarcus had been, without the skills.
You yourself say a majority of fans have the same impression of WCS. I think you need to consider that just maybe they're all correct and it's you who might be viewing him from a more kind and gentle perspective.
