Dice is one of the classiest dudes in the league. And IMO he'd be a perfect fit for the Spurs. His focus and professionalism is off the charts.
As others mentioned, he returned to Detroit out of a sense of personal obligation to Dumars for believing in him when most of the league figured he was done. Having a level of comfort with his teammates/coaches/organization was also big on his reasons. He also thought the world of strength and conditioning coach Arnie Kander (the same guy Grant Hill wanted to pay to come to Orlando), crediting him for his return to revelance as a player. He could have gone anywhere. Plenty of teams wanted him, including legit contenders.
And despite his desire to win a ring, he's said over and over that he's not going to be one of these guys that chases a ring at the end of his career. In some ways I almost think he's come to terms with the idea that he'll end up finishing his career w/out a Championship. He's had his opportunities, and that's that.
With the Pistons expected to heavily pursue Boozer and another FA (Ben Gordon) with their $20M, there's likely no money left for Dice. So he'll either retire or find a team where he and his family will feel comfortable.
If we don't get Boozer ... and he's yet to opt out ... there's a very good chance we sign him to a one year deal, allowing him to recoup the money he lost in the Billups trade.
He's still got alot of game left in him. More than I expected. His lateral quickness isn't the best. His hands aren't great. He's more of a jump shooter than a true post player. But he doesn't quit, fights for rebounds, and understands the game.
I'd love to see him sign w/ the Spurs, win it all, and finally be recognized as the Champion he is.
