Here's the full early FOX group (gray denotes no early broadcast game on FOX):
Green - Cardinals at Rams
Not a ton of extraneous markets getting the game this week. Seattle @ Minnesota is blanketing the national coverage with playoff implications and Atlanta-Tampa is soaking up SEC country. Not a ton of room for Rams-Cards or 49ers-Bears.
As it is, the Rams get all of Missouri save for a Kansas City-driven cesta in the northwest. Sliver watch this week: Iowa, Illinois, Kentucky, Tennessee, Arkansas, Oklahoma, Kansas.
The Cards' market drives in nearly all of Arizona without the 191 corridor. And the Yuma-El Centro band in southeast Cali gets the game as well.
If the Rams continue to fall in the standings, these broadcast clouds are just going to get smaller and smaller.
