Yu Fei and Durant's conversation was limited to just the two of them.
But for the SuperSonics, its significance extended beyond the two individuals.
While they discussed the matter, other players were present, as well as the coaching staff. Everyone just pretended to busy themselves, as if a group of lower-ranked players couldn't grasp the thought processes of those ranked higher. They ignored the dialogue between Yu and Durant while trying to appear occupied.
Their body language was: Sorry, I can't hear what you're saying.
However, outward indifference did not mean they could genuinely ignore it.
Yu Fei and Durant were people who could influence the team's internal hierarchy. When the former discussed with the latter about which year's Kobe he wanted to become, he was indirectly asking the other teammates.
Do you recognize this "Kobe"? If Durant really has a Kobe he aspires to be, would you support him?
