It has nothing to do with coaching, but the players ability to understand and adjust to what they see. You can only teach so much. These players have 1000s of practice hours over their time as players. Some things require natural mental ability.
lets just whiff the guy I need to tackle. no big deal. its not like I was recruited to tackle people. I mean, he's already so close to the goal, why not?! They'll probably score anyway! Whiff! Sorry coach! I thought I had him.
