Communication is key in football. That ability to connect is so important in every department of the game, sure, but nowhere more so than in the relationships a coach has to forge with players. Without those relationships, a team is just a group of individuals, and a coach nothing more than a manager of disconnected talents.
Programs searching far and wide for talent across the globe has made that communication learning curve for coaches steeper than it has ever been. Staffs must be able to communicate on an international level, and bridge the gap between not just race and class, but sometimes between entirely different languages and international cultures.
