My only point is that playing the center position doesn't seem to make a difference regarding the coaching ability for it.
I was just asking anyone (didn't mean to point you out) if there were any stats or empirical knowledge to back up the repeated assertion I read here that basketball coaches who played center would be the best coaches for that position. Thought there might be some evidence I wasn't aware about. I do agree that our centers haven't progressed like we'd have liked to. Bernie Fine was known as a big man expert but he didn't even play the game.
