The fan, 72-year-old Irving Bierman, requested that Dolan "Sell [the Knicks] so their fans can at least look forward to growing them in a positive direction."
On Friday, Dolan explained why he replied to Bierman. From the Post:
"Here's what happened: I was sent a bad, hateful email," Dolan said. "I get emails all the time, like I'm sure you understand. I generally don’t respond to the bad ones. This one, it caught me at the wrong moment and I responded sort of like tit for tat.
"I knew I shouldn’t have done that, but I did it anyway because it made me angry — it was a personal, hateful attack. Basically it's over and we got All-Star Weekend. I'd love it if we all just focused on that."
NBA commissioner Adam Silver told the paper Monday that Dolan will not be punished for the email.
