Kyrie Irving (PG) - Player option for $18,868,625, Age: 27

Many believe that Wednesday was Irving's last game with the Celtics. The six-time All-Star is coming off a season in which he averaged career-bests in assists (6.9) and rebounding (5.0). He shot close to 50 percent from the field and slightly over 40 percent from deep while averaging 23.8 points per game. Yahoo Sports reported that Las Vegas actually lists the Brooklyn Nets as the favorite to land him in the offseason.
