I have an immature suggestion.

Zhang Yang retrospectively recalled that after the start of the latter half of the season, the first few games had gone well. However, by late February, as the schedule grew denser, he noticed Duncan and Ginobili, the veteran cores, becoming increasingly fatigued after each game, but at that time, he did not pay attention to this detail.

Firstly, in his memory, both were still the tactical cores of the team until the 13-14 season, playing against the Miami Heat's Big Three and almost sweeping the opposition.

Secondly, both of them were of the type to speak little when with others and would not likely mention their tiredness in front of teammates. Both were capable of shouldering responsibility without affecting the team.

Thus, Zhang Yang didn't consider this at the time.

But this time, the three consecutive losses, specifically speaking, after the double overtime battle with the Mavericks and the back-to-back games, except for Parker, the other two's performance was very poor.
