Yards At The Catch measures the yards gained by receivers at the point of the catch and before any yards after catch are considered. This tells us how many yards from scrimmage the receiver was when they caught the ball.
More about Team Yards At The Catch - YATC
Yards At The Catch can give an indication of how far on average the team throws the ball to receivers as it only considers the yards gained from the pass and not any additional yards gained by the receiver.
Additionally, teams that throw the ball further on average tend to have lower completion rates. Teams with relatively high completion rates and high average YAtC signal teams with elite passing and receiving units.
