No. The real reason involves Eddie House. I don't want two guys that short sharing the back court together. If Eddie wasn't here, and our backup at the two was a typical two, then no problem.
If our second unit played a swarming defense, then maybe, but if that were the case, then that would be better suited for younger guys. Doc rarely has ever played that style for the second unit.
Either way, I think three months of Marbury was plenty. He worked hard, but he's not a good fit.
