I Think they should but only on MNF, Thanksgiving games and Playoffs. If Game is on sundays it can get blacked out if game isn't soldout. And you can only black it out it team in your city where TV station is located. Like for example if the Raiders don't sellout they cant show it in Oakland -SF bay area but they can show it in San Jose. If Dolphins are blacked out you cant show it on Miami TV channel but you can show it on West Palm Beach channel. If Eagles are blacked out you cant show it on Philadelphia TV channel but you can show it on York and Hershey PA channel. You get the idea. I think its time for this law since the NFL is making money though advertisements.
