I will get out my crayons and draw you a picture, maybe then you can understand (although with your intelligence I highly doubt it)
Thanksgiving is a national holiday. There are only two games scheduled that day, one at 12:30 and one at 4:30
Both are centered roughly around meal time for Thanksgiving dinner. One game for the East Coast, One for the West coast.
The games have a National audience, this is what defines them as "prime time games"
Your pathetic attempt to try to define what is prime time and what is not is disingenuous.
Average viewership for an NFL game is 17.1 million
Viewership for the thanksgiving game (2021) for the Lions was 26.9 million , and then 29.7 million for the Cowboys.
Viewership for one of your "Prime time" Monday night games was significantly lower.
By comparison, the Bears - Steelers Monday night game drew under 13 million viewers
Now take another L and run along spanky, you are embarrassing yourself
