Seattle is also missing every WR (Engram and Branch are just now getting on the field this season), they're missing a capable RB (Julius Jones sucks) and they're banged up in every position, including QB with Hasselbeck who missed practice this week.
If they ever get healthy, they'll still be weaker than when Zorn was there, but they're not really AS bad as they look right now.
With that said, I can't stand Seattle and it is good to see them losers in every sport. They even lost their basketball team.
