Motivated by publicity, for tax reasons, or by good intentions? ESPN's damning report on athletes' charities, many of which "don't measure up."

"An 'Outside the Lines' investigation of 115 charities founded by high-profile, top-earning male and female athletes has found that most of their charities don't measure up to what charity experts would say is an efficient, effective use of money. Using guidelines set by nonprofit watchdogs Charity Navigator, the Better Business Bureau and the National Committee for Responsive Philanthropy, 'Outside the Lines' found that 74 percent of the nonprofits fell short of one or more acceptable nonprofit operating standards. The standards cover all sorts of aspects, such as how much money a nonprofit actually spends on charitable work as opposed to administrative expenses and whether there are enough board members overseeing the organization." -- Paula Lavigne, ESPN.com
