Jason Kidd holds the NBA single game record with 14, and his handling and passing must both be legendary. So, if a guy in the best league in the world can have 14 turnovers in a game, I don't think it is too crazy that a guy in d.5 could turn it over 16 times.
And while I agrre with you that not too many teams press full court for 48 minutes, there are teams that do. For example, every team ever coached by Jerry Tarkanian.
Once I scored a basket that still makes me laugh.
