Yeah I'm skipping both. Detroit just doesn't seem to lose big often (they even kept it very close last 2 games against Wizards and Pistons, despite Grant missing all of one game and most of the other). On the flip side, Dallas just doesn't blow out opponents very often, and is also inconsistent (they've had some massive losses in the past few weeks).
Maybe I'll see both of these games end up with 21+ margins, but this just doesn't really fit my model, so I'll pass.
