I'll make suggestions as far as play calling is concerned, but most of that work is done during the week. Footwork and hand position and body placement are important to every player. Without effort, of course, you have no chance of winning. Of the three areas, I'd say communication is the least obvious and the least understood. I thought it might be interesting to discuss it this week.
Communication takes many forms in football.
It starts in the classroom, where the coaches lay out the hows, whats, whens, wheres, and whys for the players. It carries over to the practice field. And it's absolutely vital during the ball game. You might be surprised to hear how many different types of communication are going on during an NFL game. The interior linemen communicate with one another to adjust blocking assignments.
