Nope, Kidd was brought in partly because of Winstons anaylsis on clutch play. It was a trade berated by many, including myself but Harris was a flash in the pan and Kidd's clutch play inevitably played a greater role than Harris ever could. Seriously read up on them, at least if you intend on bashing the revolution.Obviously that team was led by Dirk which arrived long before. Same with Terry/Kidd.
WW helped identify Rick Carlisle's propensity for playing optimal lineups, which played a role in his hire. Not sold on your Chandler theory.Bringing in Chandler was obviously due to Cuban's checkbook more than a statistician finding some hidden gem. So how much credit would you give?
He has helped as a tacticion in terms of lineup analysis dating back to the Rockets series IIRC.
