Even if it did, and I don't think it does, it would be such an insignificant # I don't think it would be noticeable....My NYU team, which was good but not great, turned the ball over about 12 times a game against decent non press teams running normal tempo.......If there was a 10% increase in turnovers due to slow down (which would be a very high percentage) you're talking about less than 1 to per game when you factor in the reduced possessions....Any increase in turnovers is more likely do the reasons why you would choose to use slow down
