Northwestern football players will cast secret ballots Friday, April 25, 2014, on whether to form the nation’s first union for college athletes, a potentially landmark vote that will, however, be kept sealed for weeks or months, and possibly years. There has been plenty of lobbying in the form private meetings, calls and emails, and everyone from coach Pat Fitzgerald to NCAA President Mark Emmert has called for a “no” vote. (AP Photo/M.
