Other than Who a couple posts back, no one has brought up the fact that, with this trade, Detroit becomes positioned to make a huge revamping of its team thanks to ridiculous amounts of expiring contracts this season.
AI represents $21 mil, Sheed nearly another $14 mil. They've cleared Billups and McDyess' numbers off of next year's payroll (about $19 mil saved).
They just locked up Maxiell for about $5 mil a year for the next 4 years. By my rough estimate, the Pistons have somewhere around $38 mil in guaranteed money for next year, assuming they don't trade Rip Hamilton for another expiring deal. They can either trade those expiring contracts for younger talent, or let them come off the books and land a big-time free agent (Wade, Melo, etc.) this summer to round out the Stuckey/Afflalo/Amir/Maxiell/Prince core.
Joe D will be busy this season.
