In sports, you rarely see a team pop up out of nowhere and win it all. An unfortunate truth of the nature of sports is that it might take four or five cracks with the same nucleus to get over the top. The Celtics finally got over the hump by adding strong reinforcements to their core centered around Jayson Tatum and Jaylen Brown. The Nuggets got over the hump as their core of Nikola Jokic, Jamal Murray, and Michael Porter Jr. matured under coach Michael Malone. The duo of Giannis Antetokounmpo and Khris Middleton took several years to make and win the NBA Finals.
