After hours of rain delays and facing the threat of more, the organizers of the Daytona 500 have opted to reschedule the race for noon Monday. It's the first time weather has ever forced the competition to be held on a different day, although it has been shortened on four occasions. While moving the race to a weekday afternoon will inevitably mean much lower ratings for Fox Sports, it does have the benefit of easing what would otherwise have been a rare pileup of marquee live events in prime time.
