A lot goes into winning a championship.
First and foremost, you need the right players and some superstar talent. Obviously the Cleveland Cavaliers don’t win without LeBron James and Kyrie Irving and the Los Angeles Lakers don’t win without Shaquille O’Neal and Kobe Bryant. This goes without saying (even though I just said it).
You need a good supporting cast because rarely can one superstar lift an entire team to a title (although James has come close). You need a good coach — one who doesn’t panic when shit hits the fan and who can adjust on the fly.
