I have always wished the Super Bowl was on Saturday. According to Deadspin ESPN, I am not alone. They asked if it should be moved to Saturday and 57% of people said . . . yes, let's move it. 

The divide is down the center of the country . . . people in the Eastern and Central time zones really want Saturday.  Unlike the two western time zones, they don't have the luxury of making a full recovery and getting a full night's sleep after the game.
