I believe it's a hiccup with the system. They are only supposed to blackout 1 team, the closest one to you, i.e. your local team. Blacking out multiple teams, or any really is complete garbage. I understand the local team because of TV contracts, but 4 teams? Come on man!
No. Its if there is a provider that is providing that teams broadcasts in your IP address they black it out. The Kings are blacked out because the Maloofs had a contract to broadcast their games in Vegas because that was their base of business
