The Showtime Documentary Perfect In ‘76 airs tonight (9 p.m., ET, PT), detailing the Indiana Hoosiers team that became the last college men's squad to have an undefeated season. Singer John Mellencamp narrates, and the press release claims that it takes us through "all of the highs and lows that came with it."

Some who have seen it, however, say the documentary does little to address coach Bobby Knight's dark side, but you'll have to decide for yourself.

For a more complete look at Knight's personality, one just has to listen to him. He appeared on The Dan Patrick Show today, and had some revealing things to say. For one, he emphatically insisted that he's never again setting foot on the Indiana campus -- he was fired in September of 2000 after refusing to resign following a series of incidents that, says the University, violated a "zero tolerance" policy on his behavior.

Is Bobby Knight bitter? Oh, not at all!

PATRICK: "Aren't most of those people all out of there now, coach?"

KNIGHT: "I hope they're all dead."

I know that some consider Knight the greatest basketball coach of all time, but for me that's not true. Pete Newell was probably the best, and there were a couple of others. But as far as x's and o's, he is definitely one of my idols.

It's too bad that I can only say that after splitting him into two people, however. The structure of his life off the court was as flawed as the structure on it was sublime. I compare his coaching brilliance to the dragon you release from the pit to help you conquer Westeros -- but then when that's done, there's all the dead innocent civilians and charred livestock.

Tonight we can watch the Showtime doc and just focus on basketball Knight, and that's good. But thanks to Dan Patrick for reminding us that the other Knight exists. We should never forget that.
