The two CBS games are Jacksonville and Tennessee. I don't see CBS putting much effort into either one of those games.
Games that should garner the most national interest in order that I perceive the national media (ie includes my own bias)
Niners (both games should be huge, given that we are the top two teams in the NFC by most accounts)
NY Giants (always a media darling, only 2nd because of the Niner rivalry)
Falcons (rematch from the playoffs)
Colts (Luck vs. Wilson and both playoff teams)
Saints (this really depends on how they are doing, but there is a reasonable shot they are playoff contenders, just depends on when we play them)
St. Louis (2nd game, and this is a HUGE if and only if they are in contention for a wildcard game later in the season)
Minnesota (given the fact we have Rice & Harvin now, could garner some interest, but will also depend heavily on when it is in the season and if they are out of contention)
Houston (not really much of a market, but if they are playing well enough at the right time of the season it could get a good amount of attention.
Games that won't garner much interest outside local markets
Carolina, Arizona (x2), Jacksonville, Tennessee, St Louis (1st game) & Tampa Bay
