All true, but I think a certain number of turnovers is acceptable, and pretty much necessary. If you never turn the ball over, you probably aren't being aggressive enough. It's just a fine line between aggression and carelessness.
One of my pet peeve's is when football coaches or analysts say something like "The team that wins the turnover battle will win this game". Ok, just have your offense take a knee every play then. You'll be guaranteed to win as long as you don't turn it over.
Point being, in order to make plays and try to win the game, you will risk turning the ball over to some degree. It's inevitable. For basketball, I feel like if we're at 12 or less for a game, that's pretty acceptable. Less than 10 is really good.
