I don't remember Ceal's best teams turning the ball over much at all. They loved to run, especially with Shelley Sheetz at the point, but I don't recall that they had a lot of turnovers. Now, my recollection could be clouded by their success, so maybe some of the other old ****s can add to this.
I also think that the type of turnover is more important than how many you have. Lazy turnovers -- travelling, bad passes while running the half-court offense, having the ball stolen off the dribble, etc -- are not good ever. Aggressive turnovers -- trying to thread a pass while on a fast break but missing, and the like -- are more forgiveable as long as they are somewhat limited.
