The problem is when people try to use statistics to prove their agenda rather than to reflect reality.
The problem is Dak isn't able to beat good defenses and good teams through the air, and time after time that will catch up with this team. Will, you beat poor teams like the Giants? Maybe. Will you occasionally beat a good team? Sure. Will you win consistently enough to make it through the playoffs? I seriously doubt it.
In this game the defense won the game. What happens when you play a team with a QB better than Eli? An offense more consistent that the Giants, who by the way rank 29th in the league in points per game (guess who they are tied with, the Cowboys...). Dallas is also 30th in yards.
So yeah, you can beat poor teams, but when you play good teams, and we will, we're going to struggle.
