Kesler's success as a player has been attributed to his competitiveness and desire to outwork opposing players. Kesler has recognized, however, that his competitive drive has often caused him to lose his composure. In the 2010 off-season, Canucks management encouraged him to play with more focus, maintaining his emotions and decreasing physical and verbal confrontation with opposing players. During the subsequent 2010–11 campaign, he gained media attention for changing his play accordingly while enjoying the best season of his career. Kesler has also credited the change with his role as a father, wanting to set a mature example for his children when they watch him play.
