Nikola Jokic and Joel Embiid are the NBA's main men in the middle, the two centers combining for the last three MVP awards in the regular season with perhaps another coming soon. Jokic cemented his place among the game's greats by leading the Denver Nuggets to last year's NBA title, and he appears intent on staying on top. Jokic will try to lead the Nuggets to a 2-0 lead over the Los Angeles Lakers on Monday, while the Philadelphia 76ers hope Embiid can help them tie up their series against the New York Knicks.
