James L. Edwards III: The Pistons need to find out if Duren’s struggles defensively are due to his inexperience, the team’s bad situation or if it is an area they’re worried won’t get much better. Duren has a lot of potential — I’d be afraid to trade him — but that potential won’t be reached until he turns a corner defensively. It wouldn’t surprise me if Detroit elected to bring in a more seasoned center in order to lessen Duren’s workload and allow him to develop without the stakes being so high .
