George Karl: I heard @MarkJackson13 is taking shots at my defensive coaching during tonight’s broadcast. Remind me, how many all-star teams did you coach, Mark? How many DPOYs? How many Finals appearances? How many of my teams became dynasties right after I left? Mark Jackson: Wasn’t even thinking of u! Btw I never lost to u in the playoffs as a Player or as a Coach! God Bless u and urs!
