Turnover percentage measures the rate/number of turnovers that occurs when a player has the ball in their hands.
Well but on some level that's literally not true, right?
Tyler Kolek is the nation's assist leader, and the turnovers he commits are almost never when the ball is in his hands, it's when he plays a pass that's a little over-ambitious or not on the same wavelength as a teammate. He takes WAY more chances with the ball than someone like Domask does, because that's his game.
Domask is a great passer, but Tyler Kolek generates massively more offense from his passing than Domask does.
It's not like I'm inventing the concept of AST/TO ratio here. That has been a common basketball stat since before the analytics revolution.
Some of the best ballhandlers who ever lived were NBA leaders in turnovers, Isiah Thomas, Allen Iverson, Steve Nash, in all cases the juice was worth the squeeze because of the offense generated by taking those risks with the ball.
At the end of the day saying Domask is an elite ballhandler is like saying Zach Edey is an elite free throw shooter. Both are remarkably good given their limitations and are way better than you would expect, but like, they aren't GOOD good, and it would be weird to pretend otherwise.
