Yep. They would actually make more money on a per-game or per-team basis by charging outrageous amounts. That needs to be regulated too.
I don't see why they can't offer both packages: all-games for X price; your favorite team for X x 2 price.
I still like to see other teams play outside of the regional coverage.
Besides, if anyone is still paying $200 or more for NFL Sunday Ticket, they're getting ripped off. Beyond the first season, I've never paid more than $200 for the Ticket. For the past few years, I've received the Ticket for $159, $150, $139, $129 and discounts for free movie channels for six months or some money off my bill. That's $38 a month or less to watch any game you want to. Heck, I spend more money than that on groceries. I'll take it.
