CLEVELAND, Ohio - In a move expected by many, Cavaliers' forward Mike Miller made it official on Monday by exercising his player option for the 2015-16 season.

Miller, 35, will earn $2.8 million next season. He had a deadline of June 29 to notify the Cavaliers that he would be returning. If he opted to decline his option, he would have become an unrestricted free agent.

Considering his performance this past season, opting out was never a possibility.

The 15-year sharpshooter had the worst season of his career in his first season in Cleveland. His numbers across the board were career-lows. He never fully gained the trust of Head Coach David Blatt. When Blatt did give him a look, his shot was practically nonexistent.

He appeared in 52 games and averaged 2.1 points while shooting 32 percent from three-point range. The Cavaliers knew midway in the season that Miller was opting in.
