I know you were discussing this with Kingsgurl, but since it's something she and I have talked about several times, I thought I'd add my three cents:
With almost everyone else on the team, it's fairly obvious they play the game because they love it. They're good at it, they make lots of money at it - true. But, bottom line, they LOVE the game.
With Pedja, it's different. As you pointed out, the game of basketball has been a tool for him. It helped him help his family; it has provided him with satisfaction at the International level, which I understand is much more important to most Europeans than an NBA title. But is it a passion with him or a job? That's why we wonder what his motivation is...
We've wondered that if it's a job and NOT a passion, maybe he just needed a vacation - which he finally got this summer.
I think, regardless of what caused the problems in the off-season, it is clear that Pedja is back at least mentally into being a Sacramento King. It's pretty easy to spot - his skills may not be totally at peak but he's interacting with the team, the fans, etc.
At this point I think the question can be laid to rest. Unless he's an extremely good actor - which I do not believe after those GOOD FEET commercials - he's being pretty honest about his feelings for his teammates, his family, his life here, etc. The drama is over - I'm hoping there won't be a sequel.
