11. Kyrie Irving
Kyrie Irving was in the midst of a great first season with the Celtics last year and was ready to lead them into the playoffs when a knee injury sidelined him for the remainder of the season.
Without Irving, the Celtics still made it to Game 7 of the Eastern Conference Finals but were unable to beat LeBron James and the Cleveland Cavaliers. If they had Irving in tow, the Celtics likely would have ended LeBron’s Finals streak and would have had a shot to take down the Warriors in the 2018 NBA Finals.
