What was Joe Dumars thinking when he traded for Allen Iverson?

Before this season began, I was once again hyped for the Pistons to once again make a deep playoff run. With basically everyone returning and Jason Maxiell finally getting his time, there was no way to go but up. However, something about the coaching situation didn't sit easy with me. I watched the Pistons when Michael Curry actually played for them, and that was not exactly when they were championship contenders. He has no prior NBA coaching experience and is a defensive minded player which would probably translate into his coaching strategies. First of all, the Pistons are and were already a heavily defensive squad that if anything, needed an improvement on the offensive side of the ball. I guess that is what Joe Dumars was trying to do by trading for Allen Iverson, but if anything, if you are going to give up someone as prominent and clutch as Chauncey, why would you let him go for someone who is on the decline of their career. Not to discount the skill and grit of Allen Iverson, but the answer is just not himself anymore. We do not need two "grandpas" so to speak on the floor as one time. (Iverson and Wallace) The front office should have given him up for a younger talent or just kept him. Even though the season has not been going that well, there have been some bright spots in Maxiell and Stuckey. Stuckey has by far lived up to the expectation that the Pistons had for him when he was drafted. It is certainly an upgrade from the bust who is Darko Milicic. If you take a look at the Pistons record and then the Nuggets records, it is clear to see who got the better deal. Iverson has never really had success without himself being the one superstar for his team. Richard Hamilton has since lost touch with his game and it is clear that he misses the fluidity and basketball knowledge that Billups possessed with his time in Detroit. The Pistons will probably end up with a low seed and be eliminated in the first or second round by the way things are looking. It's going to be a long season, but don't give up just yet. The future looks bright with Maxiell, Prince, and Stuckey if they remain in a Piston uniform.
