yes, I severally watch passing stats. I don't make a decision to change passing stats based upon that though; but will make a decision to change mentality based upon that. If opponent has high completion %, he's passing short, so I know not to park the bus. If he has a low completion percentage, he's bombing long balls, so I know not to attack and press high, since the long balls will reach his strikers with my defenders pressing up the pitch out of position.
