Hosting a event such as the Superbowl on a Sunday limits the potential this great day has.  Moving the Superbowl to a Saturday will give many more people the ability to watch the Superbowl from start to finish.  I believe moving the Superbowl to a Saturday to alleviate the stress that comes a long with hosting the event and then having to work the day after.  With a buffer day after the Superbowl will allow many of us fans of football to fully enjoy this day to its' maximum potential, we waited an entire year for.
