Correct if I'm wrong but the main things learned from this game (in the preseason mind you) is that:
Brandon Jackson looked good- All but assuring himself the starting rb spot for the Packers
James Jones looked good- lock for 3rd wide receiver but also a possible threat to Jennings
Seattle's offensive line looked bad- missing both starting tackles but pretty bad regardless
Anything I missed?
Packers are going to lead the league in sacks - #2 last year(?), and this year to date they show no signs of letting up. There will be a few pack d line on peoples IDP teams. Packers secondary looked better than last year - but it was against the seagirls 3rd string. They have to prove themselves still.
Having said that, if the pack D is back, the pack will win alot of games. Getting two def TD and great postion makes it easy to win games. If the Packers develop a 3rd lb and some secondary to help their two all pros....
