Yes, you are missing something. They have 1st and 2nd half lines. When you go into the NBA lines, click on the tab at the top that says "First Halves", "Halftimes", and even "Quarter Lines"...
They are usually out later in the day and they usually don't have them overnight. <a href="http://www.newbodog.com/welcome/74880.html" target="_blank">Bodog</a> has their own lines. They are one of the few books that don't pull their overnight lines from Vegas. So, they usually don't have overnights for any exotic wagers. That's actually one of their downfalls. You have to be patient sometimes for their lines.
But, in a world where you just don't trust your money in other's hands, I have 100% confidence that your money is safe with <a href="http://www.newbodog.com/welcome/74880.html" target="_blank">Bodog</a>. That goes a long way in my eyes.
