Let's try a little game. I'm going to pose a series of three questions, and you will answer them one by one in your head. Don't follow the link until you've answered all three.
In your head, picture a football game. The offense has the ball and is about to pass. Don't consider YAC, but only the position of the catch itself relative to the first down line.
1.) It's third down. Where, relative to the televised yellow first down line and within +/- 2 yards of the line, is the most difficult distance to complete a pass to? I'm looking for a distance from the first down line, so horizontal distance from the quarterback is irrelevant at this moment.
2.) It's second down. Same question.
3.) First down. Again.
The answers can be found here.
How did you do?
