Focus, for anyone, is essential to accomplish what needs to be done. In coaching a QB it is critical to find ways to impress on him how important it is for him to control his mind and zero in on the task at hand and not be distracted by all the ouside noise. Positive thinking is a major part of being successful.
A golfer standing behind his golf ball is visualizing the shot he wants to execute. Before it happens he sees it happening. A QB is no different, he sees himself making plays days before they are ever made.
Most every QB I have ever coached has had to sit on the couch, after dinner, and watch the movie "For Love of the Game" with Kevin Costner. It is a bit of a love story, tied into the perfromance of an aging Detroit Tiger baseball pitcher. In the movie the cinematography is fantastic. Kevin is standing on the pitcher's mound, getting ready to throw, all the Yankee fans are yelling and screaming negative things at him. He listens, as he stands there, but when it comes time to pitch he says to himself "control the mechanism", he zeroes in on the catcher's glove and the movie then shows all the fans yelling but the viewer, and Kevin, don't hear the noise, he has blocked it out.
He ends up pitching a perfect game.
In order to win, or succeed, it becomes necessary for all of us to block out the noise and just focus on the task at hand. See the target and hit it, throw the completion!.
