If your Quarterback struggles with this read it can sink the play, unless you find a way to clean up the read for the Quarterback.
A guiding principle in coaching football is to do what your players are good at. If your players are not able to complete their assignments on each play, then the play will never work. While skill development does have a significant role in the improving these skills, it’s equally important to focus on the plays that your players are already good at. This is even more important when dealing with a Quarterback as they are the only player on the offense who will touch the ball and make a decision on almost every play.
