The largest part of the problem is ego and perspective. Don, like many great players, think they can be or are the best player in the league. They literally think that and believe the far majority of their team’s failures lie on their teammates. That if their teammates simply stepped their game up, or their teammates were better, they’d be able to win a ring.
Which is the problem. What these great players fail to realize is they are not transcendent superstars. They aren’t Lebron, Giannis, or even Durant or Doncic with a combination of unGodly skill and size. Little 6’2” Donnie has his own dick stuffed in his mouth, blind to the fact that he’ll never be those guys ever. It’s physically impossible. He will simply never be that great and since he can’t shoot like Steph Curry, he won’t be him either. To guys like that, the game is simple. For skill and/or physical profile reasons. Not for Don. He has to work his *** off for everything he gets on the court. It’s difficult. So once Don realizes his only way of winning it here will be to embrace his teammates, take accountability, play some lockdown defense to set the example and watch his teammates follow, the quicker the team will improve and actually have a chance at winning it all.
