The Dallas Cowboys won their first preseason game against the Miami Dolphins, but it was far from a dominant performance. They'll look to change that against an Oakland Raiders team which is in transition and with yet another new quarterback.

There is always a lot to watch in the Black Hole at Oakland, but here are three things to watch which will happen on the field, not in the stands, when things kick off at 10PM est.

1) Matt Flynn lost out on a starting gig in Seattle last year, but has a firmer handle on things this time around. He can probably secure his starting job with a good performance in the next two games, if not sooner. We're not sure what to make of Flynn, given the very little history we have to go on.

2) The offensive line was OK last week, but could play better. The Raiders have a decent defense, but in terms of pass rush the Cowboys should be able to keep their quarterbacks upright. Travis Frederick was a much maligned first round pick by the Cowboys, but he had a very nice game against the Dolphins. Following it up with a good performance against the Raiders will make the Cowboys very pleased.

3) Along with Flynn, the Raiders are hoping for some pleasant surprises from among their wide receivers. Denarius Moore has shown promise, as has Rod Streater. Jacoby Ford and Juron Criner both have raw skill to build on as well. The Raiders need Matt Flynn to succeed and in order to do that, they need his weapons to help him out.
