The offense and defense work off of each other. If a QB has a good handle on the game , he usually doesn’t put the defense in bad spots. Turnovers, clock management, situational awareness, clutch plays all matter more to me than box scores. If that wasn’t the case why even watch the game?
For example if a QB throws a pick 6 , and then gets the ball back and drives 80 yards for a TD it looks ok on a stat sheet, but that’s not at all ok. Also what if the team scores on special teams thereby not allowing the quarterback to put up numbers?
