You're doing it wrong.
You want to read the autobiographies of guys who were average to good, not the all time greats who have nothing interesting to say because they have legacies to protect.
Sobers one could be interesting if it delves into issues of race, black players playing opposition who were mostly white at a time when the ICC still stood for Imperial Cricket Conference.
Michael Atherton and Nasser Hussain's autobiographies are great. Simon Hughes has a really good one as well, Mushtaq Mohammed's might have been OK, I can't really remember much about that one. Miandad's was boring.
I want to get around to reading Jonathan Trott's autobiography, I reckon that will be brilliant. Trescothick as well. Reading about the problems and insecurites faced by players is far more interesting and gives you a real insight into how those people tick than a few hundred pages of "I practiced loads when I was a kid, grew up and scored a billion runs, I'm bloody amazing aren't I?" things that you'd get from the bigger names.
