NASCAR will hold a press conference this afternoon in Charlotte, North Carolina, to reportedly announce the details of a new “charter system” for Sprint Cup teams. The agreement is expected to guarantee an allotment of starting spots for certain team owners and shrink race fields to forty cars, down from the current forty-three. The system would provide owners with additional revenue and create more value for their teams … The press conference will be streamed live at MRN.com and on the MRN App.
