Miller has no trouble telling the world how great he was. He also has no trouble telling the world how awful he's become.
In his book "I Call the Shots," he devotes a chapter to choking, and puts himself at the head of the list. He freely admits his putting nerves drove him off the tour, and he even lists seven or eight different ways he tried to combat (sometimes successfully, but only for a while) the yips.
The guy is honest. He defends his honesty by saying he doesn't dislike anybody, so he's not worried if his opinions are taken as mean-spirited, because that's now how they are intended.
Then he lets the chips fall where they may. If he thinks he did something great, he tells you. If he thinks a famous pro did something badly, he tells you. And vice versa, in both cases.
That style will never play well with all the people, but I'm sure glad NBC convinced him to take a broadcast job. I'd rather listen to Miller's version of what's going on during a tournament than any since Henry Longhurst.
