I completely agree with you. we've noticed it in every game we've played. they rarely tip balls. if it is near them they will pick it or if it's thrown right to them they pick it. In real football this does not happen but hardly at all. So many drop the ball regardless of how easy of a pick it should have been. infact id say more are dropped then caught.
We turned down interceptions for the CPU to 30 to see how the gameplay is, not that we will notice any diff other than them not going for picks but it's worth a shot.
And it very well may just be madden. which i'm believing to be the case anyway, i'm in denial haha
