Ray Allen has made some interesting decisions over the past few summers. In 2012, he decided to sign with the Heat rather than the Celtics. In 2013, he exercised his option to remain in Miami for at least one more season. And another decision comes this summer, when Allen will decide whether to continue his NBA career.

Allen is a free agent-to-be and will turn 39 next month. And while it appears he has plenty left in his finely tuned body, the guard said retirement is an option. He would likely receive his share of offers this summer.

“I guess everything [is factored into the decision],” he said Thursday before the Heat lost to the Spurs, 107-86, in Game 4 of the NBA Finals. “You get away from it, you sit down and get an opportunity to think about it. It depends on how my body feels. I love the condition I’ve been in over the last couple of years. It’s just a natural progression.”

Allen said he has enjoyed playing with considerably younger players, downplaying the generation gap.

“I don’t look at this as an age thing for me, it’s never been an age thing,” said Allen, who was averaging 9.6 points in the playoffs entering Game 4. “I always laugh because I see the birthdates of the some of the younger guys. They’re born in the ’90s. In the ’90s! I was kicking it hard in the ’90s.

“So, being in the locker room with younger guys, you talk about the athleticism, you talk about the strength, if anything, it rubs off on you to always keep your mind sharp, to always keep your body on point. The weight room stares at you every time you walk into the locker room. It’s just hard to not want to keep up or set the tone.”
