While NFL football is not a regional sport the way that baseball is, fans are still at the mercy of regional broadcast market when it comes to watching games—with a few obvious exceptions.
There are several nationally televised games each week, typically on Thursday, Sunday and Monday nights. Fans can also watch out-of-market games with a subscription to DirecTV's Sunday Ticket. Otherwise, your Sunday afternoon options are limited to whatever local CBS and Fox affiliates have programmed.
For fans of out-of-market teams, preparation is key. If your favorite team will be on the local broadcast, great!
