While calling plays is a significant part of establishing success on the field, it is not nearly as important as developing confidence in the players.
Calling plays is one of the most stressful and rewarding experiences in football. There is no other sport such a large amount of pressure is put on the coach. From an outside perspective any call could result in a huge gain or a huge loss which might change the course of the game.
In the end though, I am not a believer in the fact that play calls really change games, the majority of times it is players simply executing better than their opponent that changes the game.
The first thing to keep in mind when calling plays is to have a system. It’s critical that you have an offensive system that has the ability to attack all parts of the field. The majority of offensive systems are based around a dominant play. This play is the thing that your team has the ability to run against almost any defense and experience success.
