 When he was twenty, the National Post described Raonic as a "hothead whose on-court demeanour was holding him back." As he grew older, commentators came to see him as "stoic", "robotic", and "emotionless", with The Daily Telegraph referring to him as "an analytical character who questions everything he does in practice". In 2014, Raonic explained: "I 'm the son of two engineers, so everything is a numbers and calculation game." In 2016, he added: "I am very systematic in how [I] need to go about things to bring out the best tennis for myself, and maybe that comes off as mechanical and robotic and those kind of things, but I don't know if I 'd ever change that because I feel that's the way I get the best out of myself when it comes to my tennis."
