When these two teams meet Friday night at 8pm EST, there will be absolutely nothing extra on the line. It's not as if there is a little something extra in terms of recent history between the Green Bay Packers and Seattle Seahawks.

Aside from lingering animosity, there really are some good reasons to pay attention to the game. Here are three things which should attract your eye.

1) For all the tumult after Bryan Bulaga went down this summer, the offensive line had kept the quarterbacks from being sacked more often than not, only allowing 4 sacks in two games. That said, this will be their biggest test, as the Seahawks' front seven actually got better this offseason. Rookie left tackle David Bakhtiari has had some good moments and the rest of the line is holding up relatively well. Expect to see a lot of pressure from Seattle though, to see where the cracks are in this line.

2) The Seahawks have accrued almost 200 yards in penalties in two games. That's a staggering display of undisciplined football. If they start losing ground due to flags, and worse if they start to give the Packers good field position, they could be in trouble. Right now, the Seahawks are outscoring their opponents, but at some point those penalties will cost them.

3) Eddie Lacy had a great first game, but CHTV favorite (well, Nagler and I maybe) DuJuan Harris got some first team reps as he returned to practice. Does Lacy still have the lead back spot? Or will Harris get a shot? Does it even matter or will the Packers just ride the hot hand? We should get a good look at that tonight, as both Harris and Lacy will see action. Lacy still probably has the edge, but there's a good chance nothing is fully decided yet.
