Ian: Great question. In order to answer this best, I just did a full search in the code for the rating. Here are the areas in which AWR is used: How quickly a defender can realize the ball is in the air to try and make a play Chance to jump offsides or false start Whether a defender tries to scoop-n-score or falls on a fumble in the correct situations How quickly receivers get into “get open” mode after a route (and where they go) Chance the WR recognizes the coverage & picks the “correct” option on an option route How quickly OL can recognize and pick up new blitzing defenders Chance for QB to predict a blitz and assign a hot route When a QB will choose to tuck and run (scramble) if nothing is open Chance a defender will try to strip the ball on a ballcarrier with bad carrying ratings Chance a defender will attempt to get his hands up to tip a ball while engaged
