For ND, some of those turnovers came from Liatu King, who piled up 5 of them. Koval's 4 came on some ill-advised passes and shuffles of the feet. What was a bit concerning was Miles picking up 5, driving into jammed areas that you mentioned.
That said, this was a big-time event and folks were juiced (pun somewhat intended)...perhaps too much. Miles will look at tape and clean it up. King will learn, as well Koval.
What won't change is ND causing turnovers. It's very hard to get used to the pressure and speed of Hidalgo, Miles and Citron.
