All sports are based on balancing both offense and defense to create a balanced attack, and business is no different. Business must keep a balance between both sales and marketing, the offense of the company, and keeping its customers happy and product fresh, the defense of the company. Many companies put too much emphasis on sales, leaving their customers unhappy, just the same way as so many prolific sports teams only focus on scoring and not on defense.
