Don't usually pay much attention to the preseason, but certain spots I like to look for games where there should be a lot of passing which usually leads to OVERS. This looks like one of them.
Dallas is set at RB with Barber and Jones the obvious 1/2. Same goes for the Raiders, who are easily set with Fargas/McFadden/Bush.
Both teams have question marks at wide receiver, meaning there should be a lot of throwing the ball to get a good look at the receivers.
Also, Dallas won't be using Romo or Kitna too much as they are the clear cut one and two. There is a position battle for the third QB spot between McGee and Carpenter, and both should get a lot of chances to throw tonight.
Lots of passing means lots of clock stopping, and could be plenty of interceptions as well today. Think this one clears 34 easy .
Good luck!
