A leopard doesn't change it's spots.
Willie is who he is and this same pattern keeps popping up the last few years.
He'll have a good stretch of a week or two where he looks like a budding star and a guy that can be a starting center on a good team for years to come. When he does that the same people will come on here prop him up saying that he's turned the corner, he's everything the team needs, and the Kings need to pay him.
Like clockwork he'll then go into a rut and have a stretch of bad games where he just gets abused in the paint and floats around in the games with his head in the clouds not doing much of anything. This time a different group of people (myself included) will come to threads like this one saying he's soft, lazy, inconsistent, etc. and that the Kings should trade him.
The reality is probably somewhere inbetween. However the fact that people are so divided on Willie and that we are continually having these debates should be a red flag in itself. Should the Kings really pay $15 Million Plus to a guy this up and down?
He's consistently inconsistent. He has improved his game but he's never going to be consistent or reach his full potential (especially defensively). He is a tremendous athlete with a sub-par motor and over-inflated self image. He's aloof, just a "different" guy. In general it's tough to count on guys like that from game to game (although there are exceptions like Dennis Rodman).
Bottom line is I would trade him now while he has good value. The Kings need to see if they can get a SF or a mid first round pick from him. Paying Willie $15+ Million a year may not kill you now but it would kill the Kings in two or three years when it comes time to start paying Fox, Buddy, Bagley, Bogi.
