From the mouth of EA/Tiburon:

Our ratings have broken down Throw Accuracy (THA) into 3 categories: short, medium and deep. While Aaron Rodgers is very accurate throwing to all parts of the field, some quarterbacks are much more accurate on short throws than deep throws. Here’s the breakdown:
- Short Accuracy – rating is the accuracy percentage of the QB on throws under 20 yards.
- Medium Accuracy – rating is the accuracy percentage of the QB on throws of 20-40 yards.
- Deep Accuracy – rating is the accuracy percentage of the QB on throws greater than 40 yards.

I was really surprised to find out that short passes go up to 20 yards. I just figured it was 10 yards. That just seems off to me.
