On the subject of tanking?
I don't think the Pistons have tried to tank one season at all since Joe D became GM. He made some miraculous moves in the early 2000s, then got us a championship getting Sheed. He then thought Stuckey was ready and let go of Billups. Second biggest mistake he made. First biggest being the signing of CV and Ben Gordon. Since the championship days, he's either drafted horribly, or let go of our good draft picks too early. And subsequently, we have sucked ever since. (Not to mention our owner died, RIP Mr. Davidson)
But Joe D has never tried to tank a season.
