It's not hard to see why Ray Allen wants to stay with Miami. (USATSI)

Throughout the Miami Heat's battle through the Eastern Conference finals against the Indiana Pacers and the NBA Finals against the San Antonio Spurs, Ray Allen mentioned a few times his team's success was justification for the tough decision he made last summer. Allen chose to leave the Boston Celtics to join the Heat to try to win titles.

After receiving much flak for it and being accused of being a traitor by some of the fan base, Allen helped prove it was the right decision when he saved Miami's season with his 3-pointer at the end of regulation in Game 6 against the Spurs. The all-time leading 3-point shooter will stay with the Heat next season, too. He exercised his player option for 2013-14. From the Heat:

The Miami HEAT announced today that guard Ray Allen has exercised his player option for the 2013-14 season. Per club policy, terms of the deal were not disclosed.

He's the perfect role player for the Heat. He spreads the floor with his 3-point shooting and is always a bad idea to leave open on a rotation. He's made more than 40 percent of his 3-pointers in four of his past five seasons. He made 41.9 percent of his 3s this past season for the Heat.
