Have any of you guys watched the video? I mean, they're showing him throw against single coverage and calling that a, "tight window," because the one defender is close to the receiver.
I've always defined tight window throws as hitting a guy between two defenders in a tight zone. This stat has redefined tight window as just having a guy within a yard. One of the plays I recall was Dez coming back to a ball after getting behind the defender. The underthrown pass caused the, "tight window." I'm not knocking Dak, just saying this stat means very little as far as accuracy because a poorly thrown ball can cause an otherwise open guy to be forced into a tight window by adjusting his route. This is true for every QB being rated by this stat, not just Dak. That's why I believe this stat is useless.
