The NBA fined Mark Jackson 25 grand for stuff he said about the Nuggets. He clearly implied George Karl is a thug. I chastised Jackson in the morning’s column for making a bunch of excuses. The league obviously thinks he went over a line — he did. Some of you will justify what Jackson did. And I know what you’ll say — that he served notice on the league to look out for Nuggets’ dirty plays. His serve cost him a lot of dough.
