First off, that's better for my point, so thanks.
I found the discrepancy. Sports-reference totals up individual turnovers, database style, so leaves out "team turnovers" (i.e. shot clock violations and the like).
So, the totals starting with the LSU game are:
8, 9, 10, 10, 9, 9, 10, 8, 8, 16 (A&M), 4, 10 (Ark) ...
...(post Zakai injury) 11, 14, 14, 18.
We were handling the ball better, Zakai goes down, we have more turnovers.
I'm only saying that because that was the point we were discussing. I don't think it's the most important stat for this team. (And, fortunately, Duke doesn't generally force a lot of turnovers.) We lost most of those game, often due to our previously impervious defense having lapses.
