Contributing to the loss

Good morning everyone. Did you sleep well? I didn't. I don't always go to bed mad after a Dallas loss but man, this one fired me up. I want to believe in this team but they keep kicking us in the pants late. By my anecdotal count, this is the fifth game since Christmas the Mavs have lost in a very painful fashion.

So I wanted to hear what you thought about things. I've posted a poll below with some of the contributing factors to the loss. If I didn't cover anything, please let me know in the comments. Let's get this conversation going.
