Poor Joe Dumars. After winning the NBA title in 2004, and returning to the Finals again the following season, things had to be feeling pretty good for Joe and his beloved Pistons. However, since Larry Brown and Flip Saunders left their head coaching positions with the team, Joe's decision-making abilities have come farther and farther into question. He has yet to make a good coaching hire since Saunders, and the signings of Charlie Villanueva and Ben Gordon are now the stuff of legends. As his debut  season with Detroit has worn on, it's been looking more and more like Josh Smith will join them in their infamy. Oh, and Darko? Don't even get me started. 

Drafting Greg Monroe and Andre Drummond were solid moves for Dumars and, on paper, the Pistons looked like a playoff team at the beginning of the season. However, with another losing season coming fast into the books, it's clear that a change needs to be made. Dumars' fate is essentially sealed this offseason, and it looks like he'll need to pack his bags, and find a new office.
