The LP on TV is actually cheaper this year. It was like $179 last year. I just ordered mine and it will let me pay it out in 4 monthly installments of $42. I don't know many people who do not blow 40+ bucks a month on garbage. I know I do. Long story short, if someone really wanted to watch the games they could come up with the cash. And for the record...I have two car notes and a house note that I am paying, so I am far from being able to just drop the cash without blinking.
From my experience in previous years, most of the Mavs home games get blacked out because they are on FOXSW. There is also a local Dallas channel that shows Mavs games, but I can't remember the name of it.
