Yep, thats what I was talking about. The awareness already has effect for CPU players, but once players are under human control awareness is of no importance.
The idea behind the delay is how quickly a player reacts in minute situations - not how they are reading the play. He'll still run and move responsively as any player, but its the jukes, swats, catches etc. the maneuvers you control with the players. This doesn't change how good the player is at these things, just how quickly they will implement them.
Say you are trying for an interception, you get the timing right - well then all good and the players catching rating comes into play to see if you intercept the ball. Thats not really play recognition, where you move to cover the play is, awareness should have more effect on the split second moments in football. So more the timing of the player than how well he reads the play.
Maybe ball carrier vision can help offset this when you are running with the ball though. Say you have a low awareness but high ball carrier vision, the delay won't be as bad. But when using the player with out the ball in his hand there is more of a delay.
Dunno. Its just a idea that popped into my head. Could be stupid in practice. I'm not thinking a massive delay, but just enough you'd notice it from a 50AWR to a 90+AWR.
