Coaching plays a big role. Superteam comes with superegos and personalities. You need a coach who can keep it all together and manage all that talent.
The second part is getting the team to buy into the concept of great defense and good ball movement on offense. Celtics and heat had legendary defenses. Laker of last year didn't not because of talent but because of coaching.
This is why the Barkley, dream, Clyde rockets failed. When you have great offensive player the ball needs to move around . There shouldnt be any settling for shot or hero ball.this is what's so shocking about the nets squad. Led by one if the best facilitators of all time and their ball movement isn't great at all. The celtics big 3 ball movement was a thing of beauty.
The third part is health. I still contest The rockets superteam involving tmac, artst, and Yao would've won it all if tmac and Yao was there also the way. We have the coaching , the role players(Kyle Lowry, Carl Landry, mt mutumbo, gluman battier, ice cream man Scola, Von wafer, Aaron Brooks all these guys went on to become started in the future but were on our bench), the great defense, and the hunger. It still bothers me that didn't get a chance
And the Knicks aren't a superteam. To say so is just idiotic. Even before stars knees failed them they weren't considered one. Damn yall love to get at that squad for no reason at all.
