Many, including myself, have defended Martin Mayhew for a long time. He was a master manipulator when it came to trades. He flipped Roy Williams for a first-round draft pick, for christ's sake. His draft record wasn't perfect, but after an abysmal 2011 class, it appeared that he learned from his mistakes and gave Detroit the pieces that were necessary to build a playoff contender. But it didn't happen.
We blamed the coaches, and maybe there was some truth to it. Regardless, these were the coaching staffs that Mayhew signed off on. At some point you have to look at the results.
