Professional athletes are rarely good at running foundations; a donor-advised fund started by Matt Stover, the Players' Philanthropy Fund provides stability and confidence.

"Professional athletes are really good at being athletes. For the most part, they're not really good at running charities.

"Former Baltimore Ravens kicker Matt Stover saw an opportunity to help his former teammates and colleagues safely and legally navigate the minefield that often comes with operating a charitable foundation -- Internal Revenue Service rules, payrolls, rent and fees. So he and a couple of partners started the Players' Philanthropy Fund."--Ed Waldman, the Pressbox
