the Rams played the Vikings, Eagles, Saints, and Seahawks twice. They also played the Titans late in the year and they ended up a wildcard

they flex out of games on SNF all the time

last year for example week 7 they flexed the Rams v 49ers out of SNF only to put the Bengals v Chiefs. The Bengals were off to a good start at the time but later collapsed. And it was also one of the lowest rated SNF games of the season

dude sorry by I keep up with this stuff
