Koufax did invest with Madoff but not sure how much. For what it's worth, Koufax is a pretty savvy business man. Back in the day he was getting paid in cash for his appearances while others were taking checks and having an IRS paper trail. I would find it hard to believe he would have all his eggs in one basket.
