As the confetti rained down on Kyrie's shoulders at the conclusion of the 2017 Finals, he didn't feel a sense of elation and joy like he did in 2016. To this day, he carries around a piece of the confetti from the postgame celebration as a constant reminder of what it took to get to the Finals, and how it felt to fall short of the goal. Kyrie 4 "Confetti" honours Kyrie's win-or-learn mentality and the memento that reminds him of the incredible experience he can learn from.
