Balance in our lives is a positve. Balance for a Quarterback is essential. In order to be accurate, which is the number one priority of a Quarterback, when he is throwing the ball, a Quarterback must be balanced. Examples of what happens when one is not are readily available by watching both the most recent Denver versus New England play off game and then the Super Bowl involving Denver and Carolina. Denver's defense was able to pressure both Tom Brady and Cam Newton to the point where neither were as effective as they had been all season long.
How many tinmes did the announcers make the statement "Cam's throw is high, again". "Cam over throws another". One of the main reasons a Quarterback will miss high is he is not balanced and is unable to follow through. Cam was forced tho throw off his back foot all night and the results were not pretty.
Throwing the football accurately requires a sequence of body movements that are choreographed. In order to be consistently accurate a Quarterback must be balanced and in total control of those movements. His feet are under him and he transfers his weight from back to front in an efficient manner. Be balanced and the results will be dramatically better.
