The NBA always teases Duncan, and the future is yours. What's going on here?

In 2007, James led the Cavaliers to the finals for the first time against the Spurs, which was swept by Duncan's GDP of 4: 0. The Spurs won the championship. Finally, Duncan hugged James and comforted him, saying: The future is yours! This is a word of encouragement to comfort the younger generation at that time, which is perfectly normal.

However, when 20 12-20 13, 20 13-20 14 continued for two seasons, the Miami Heat led by James met the old spurs in the finals. If it weren't for ray allen's lucky three points, LeBron James would reap the bitterness again. Even so, it barely tied with the Spurs, and the scene was extremely embarrassing. So, now I always tease "The future is yours". First, I mocked the Spurs for getting older and stronger, and I am not old, to show my respect to them. Second, when the league star headed by lebron james plays, when can he really take over the banner of NBA from the older generation players.
