Eh, it's just not that interesting to me to rehash everything we already know and then add that he was doing drugs and diddling other ladies. He's a football player who died young. I could see if he went from playing into a coaching career and has a legacy that reached into whole lot of other venues. He's not that interesting. Jim Brown is an interesting character to get to know. Paul Robeson is worthy of multiple stories. There is no market for a Walter Payton biography outside of talking about sex and drugs. It's completely disingenuous of Perlman to talk about wanting to go from the bad guys he wrote about to an in depth biography of a good guy and that he only stumbled across the sex and drugs along the way. You don't write that book unless you have the hook of sex and drugs to sell it. If it's done well, I still love that inside baseball, grind-of-season kinda stuff. Maybe that's why bottled sports books seem to work better when one guy follows a particular subject for a season (e.g. John Feinstein's stuff) but it can work in biographies too.
