Changes could come before Daytona 500

A number of changes to the Sprint Cup Series are rumored to be lined up before next month's Daytona 500. The series has already undergone some modifications, including the removal of some testing sessions throughout the year. There have been talks that the 16-driver, four-round Chase for the Sprint Cup might undergo some tweaks before the new season begins, which wouldn't be surprising given the mixed feelings that drivers and fans have expressed about it since the format was announced around this time last year. NASCAR makes changes to all of its series during every offseason, although these changes vary in type and complexity.
