I think it stems from the fact that the defender always went for the interception and there were times where the player shouldn't really have been in position but got the pick anyways. I didn't have any issue with it though. Basically, I looked at it as getting my DB to do what I wanted him to do. I think it could be toned down a bit and that it should be made to where the DB goes for knockdowns in situations where a interception just isn't possible. And apply the awareness where if the player isn't looking towards the ball your player does nothing even if you hit the button.
Either way, it beats covering a guy down field and wanting to go for a jump ball and having my guy reach for the sky in a 'raise the roof' fashion and completely take himself out of the play.
