I've watched literally all the Dallas games. A few things I've noticed:

Parson lines up all over, inside and outside. He's good against the run too, but he sometimes takes himself out of the play on runs.

Their Corners, especially Bland, take a lot of chances. Love needs to be very careful on out routes.

Their O Line is kinda overrated IMO. Dak, similar to Love, is damn good at escaping the rush. His release sometimes seems a little low, and he's susceptible to having his passes knocked down or tipped at the line.

Pollard is very similar to Aaron Jones as a runner. Similar to the Packers, they run inside a lot - more than outside.

They have a LOT of pass receivers beyond just Lamb.

They have a little kick returner named Turpin that if Carlson's kickoffs are as lame as last week could burn us worse than that Bears guy did.

I read that the Packers have won 4 in a row at the Cowboys stadium, 5 if you count the Super Bowl - for whatever that's worth.
