You should pick teams that will NOT be on national television...so you have more games to watch.
Why pick the Heat or Thunder? Each team has bunch of nationally televised games, as you see on this list:
So....not taking into account your local teams, I'd go with:
1. Houston Rockets
2. Phoenix Suns
3. Atlanta Hawks
4. Milwaukee Bucks
5. Indiana Pacers
You have a good mix of both East and West teams. And you can supplement all the nationally televised games with teams that are rarely on national TV.
