Justin Thomas had an extremely high 157 QB rating last year, but still averaged 1 turnover per game.
He had 5 games with no turnovers. We went 3-2 in those games.
He had 2 games with 2 or more turnovers. We went 1-1 in those games.
Our possessions are valuable and nobody wants turnovers. But there really is a limit to how much it matters in the whole scheme of things. See the above stats - there was hardly a difference in our record between high turnover games and zero turnover games at the QB position. Yea we don't want a QB who turns it over 5 times a game. But if a QB can make more plays than another and along the way has 1 or 2 turnovers, its not the end of the world. Our defense should be doing the same thing in return.
