Like someone else said, I link Knight to Indiana before I link him to Ohio State. But I'm not upset by what he does the way so many other people like to be.
He may act like a goof on the court. Actually since leaving Indiana, has he been in the news, much? I think a majority of the news was inflated by the media. They wanted stories so they wrote stories. It got pretty boring. Now that he's no longer at Indiana, maybe the media no longer cares. I don't know. (Maybe they do care, but I don't, so I haven't heard anything.)
Anyway, here's how I see it: If the guy was such a bad coach, how did he get players to go to Indiana? I would think that if he treats his players badly, he wouldn't be able to attract the players that would win him games. Since he won games, he must not be such a bad guy. And, from what I heard, he was HUGE on discipline. I remember that many years, his teams would make more free throws than their opponents would even attempt, throughout the season. He had a better-than-average graduation rate, and I don't remember hearing anything about his players getting in any trouble with the law.
So he yells (or yelled) at players, media, officials, etc. So what? Like I said, if the players didn't like him, they could transfer, or just not go to Indiana. They knew what they were getting into when they agreed to play for him.
