Multiple team owners told The Associated Press that NASCAR's most recent proposal — delivered almost two weeks ago — was one of the worst offers yet from the stock car series sanctioning body. Among the complaints: The France family, which owns NASCAR as a private company, still won't budge on making the charters permanent, the series made rollbacks from previous offers and the proposal now includes a provision that would allow the France family/NASCAR to purchase charters, which are at the heart of the series' business model.
