Seems silly after all these years. Here are some comments:

Super Bowl: Why The NFL Should Play The Game On a Saturday, Bob Warja, (Senior Writer) on January 27, 2010
- Why the Super Bowl is on Sunday: Pro football is now inseparable from the seventh day. It wasn’t always so. By Craig Harline, February 05, 2012
I am not spending a lot of time on this now. I used DuckDuckGo and Google to search for “why is the super bowl always on Sunday. The previous three links had better responses than I generally found. ESPN and the NFL did not chime in. Most response seem to think that since Sunday was NFL football day it was only natural that the Super Bowl should be held on Sunday also, no matter the consequences of the next day being a work day for many people.
