I was prepared my self so when Tim Duncan announced retirement I was upset but get over it. I thought he could play one more year because he didn't announce retirement right after season is over. He played 19 years in same franchise, why not make it two decades? I guess his body didn't let him. Arguably the greatest power forward in NBA history, enjoy your retirement.
He was not playing great the last season so he realize that he should retire, he is too fair unlike kobe bryant that needs to play to destroy the team, I wish him good luck.
Because we cannot be great all the time, you will come that you cannot play the usual way and you will become less effective because we are aging and our physical ability is affected, he is making the right decision and he deserves to be the hall of fame.
