When you look at the young stars today, they would look really impressive as their stat sheets imply. But their team record are exact opposites. You'd expect that they will gradually improve year by year and have at least respectable record in the near future, especially with lottery picks in their team's arsenal. They end up disappointing instead.
It's like their flashy stats doesn't have impact on the team. Sure, they win some games, but not enough to take them to playoffs. Players who instantly impacts winning like Embiid now seems like a rare breed these days.
Meanwhile, teams without superstars are having more success than most of the teams with one. Just look at the Hawks, Raptors, Jazz and Grizzlies. Even our own Celtics is more team-oriented than a superstar-focused. Even guys like IT, Kawhi and Curry are more of a product of a system than a sheer individual talent.
Even with terrible coaching, you should expect some fight to them and have respectable record. I mean, Lebron with Mike Brown and bunch of scrubs won 66 games. Larry Bird and David Robinson instantly transforming lottery teams into 50 win teams.
Guys like Cousins, Wiggins and Davis on the other hand, have disappointing teams. And it's not like they didn't have decent players on their roster.
