No, Durant was one of the players in the room negotiating the CBA on behalf of the NBPA. That role did not come from his bag. It came from the relationship he's built with players throughout the league. It's not just a matter of having talent. It's being willing to give time to others to help them get better.
Now we're mixing up words. I never said Kobe was a leader. I was a little loose with the word earlier, so I'm not blaming you here. What I said about Kobe is that he was a mentor, which he was to a lot of players. Him having an ego that kept him from co-existing with Shaq is not the same thing. It's just like how Lebron's always been a good teammate despite the fact that he loves to play GM. Who people are interpersonally isn't the same as who they become in media narratives or even stuff they might do away from the locker room.
Honestly, Durant letting Barkley run him is one of the main things he can warn Wemby against. No one should give a what Chuck has to say about winning. Sport media doesn't care about people. They only care about money. We've already had to see ESPN trying to manufacture trades trying to "Get Wemby help" when Victor is still trying to learn the NBA game and basic consistency. Then they compare him to a role-player like Chet for no reason other than to try to stir up controversy. Durant got a bunch of pressure from the media when he left. Giannis and Lillard got a lot of pressure when they stayed. The lesson Durant can impart is not "Stay, because the grass isn't always greener." It's, "They're going to pick at you no matter what you do. They'll never be happy, because they don't care about you as a person." I don't know if Durant truly regrets any of his moves -- and the teams that used to have him probably don't regret having him. But I do think he'd offer much more valuable commentary on the media and modern NBA that Giannis would.
No. Do you think Wemby doesn't have trainers? Do you think Barnes and Paul don't know how to spend days as pros? I don't like the implication that Wemby needs to bulk like Giannis. Giannis has a different body type that can take that muscle. Wemby has put a lot of time and money into his body already. I don't actually think he'd have any interest in throwing away that investment. I also don't get why you think Durant wouldn't also have any tips on maintaining his body. He's the one who's still very good as a 36-year-old. Giannis is still in his physical prime (and is also breaking down).
What on Earth gave you this impression? It's not actually based on any data. The NBA actually tracks players' movement nowadays. The two players are basically identical when it comes to their distance covered and average speed on the court. Giannis was the second-slowest Buck last year. You know who actually hustles all the time, doesn't take plays off and whatnot? Sochan. Out of all the rotation players still on the team, Jeremy hustled the most often. The absolute leader was Wesley, followed by Tre Jones. Giannis' teammate Andre Jackson Jr lead the NBA in movement among rotation players, so it's not even like the Bucks' system was the reason. Risacher was third in the whole league in movement.
Wemby isn't ready to carry his team to a le yet, which is why investing in moves to try to force something now like trading for Jaylen Brown. But's he's not "the help" either. Giannis conflicts with Wemby on the court. They occupy the same niche on the court but just execute field goals differently due to their skill-sets. Think Lebron and Wade in Miami, except in the Heatles' case they were both already develop superstars who were close friends and wanted to work together. Even so, it was more of a situation where they overcame a bad fit due to sheer talent. If you trade for Giannis, it's his team, and Wemby becomes something between Heatles' Bosh and Myles Turner to support that. Given the Bucks relative lack of success, I don't know if that's a good thing, even strictly on the court. Durant would be different, as you said. It would be Victor's team, but he'd have extra support, including someone who could come in a lead the charge. If everything goes right, yeah they could win a le with KD, and the team should be willing to give themselves a chance to do that if the opportunity arises. But that's not the point of the trade. It's about getting someone who will make Wemby better, and unlike Giannis, the price for Durant works perfectly fine to that end.
