I like this quote from the article:
"It's something like 78 percent of former NFL players, two years after their last game, are either bankrupt, divorced, or unemployed," Ruettgers told WAWS-TV."
Heck, I'd be unemployed, too, if I just got done making $50 million in about ten or so years of work.
If I made that kind of money, I'd take at least half of it off the table--into trusts for wife, kids, nieces, nephews, etc., and I'd do almost anything to not sign a personal guaranty (most banks will take liens on marketable securities or CDs in lieu of personal guarantees if you put up 100% security).
I'd live in a state in which your personal residence is not a bankruptcy asset, such as Florida, and I'd have a house worth double-digit millions, so that I could sell it and call it a day after any bankruptcy proceedings or plan was complete.
I don't think the NFL has any obligation to take care of players that made $50 million over the span of their career, but they should do something to educate the players on how not to go belly-up. (They may already do this, I don't know.)
