Apparently, credit to NYPost, David Stern called Mikhail Provokov and James Dolan (Nets and Knicks owners, respectively) to his office, and told them to play nice. All because Paul Pierce said Nets were gonna take NY as their city, and then Raymond Felton responded NY will always be the Knicks city.
As a New Yorker who respects and hopes for the best out of both of his home teams, I'd say mind your fucking business David Stern, no one fucking asked you.
