Drag Routes getting WR's too open

Drag routes are getting receivers ridiculously open, even on press man defense. Tight ends are getting huge leads on CB's on a drag???? In the chance the DB stays with the reciever on a drag they almost always run into another defender with then gets the receiver ridiculously open. Reward good defense!!!!! Not saying the pass shouldnt be completed but too many times people are running drags and then being able to run upfield, even in man defense, zone when im covering the flats. Force players to use their play book, route combinations, and timing. Stop allowing cheap drag routes to get so open!!!
