I stand corrected...as I watch all the replays I'm still a bit miffed at Holmgren for keeping the laces on when the momentum was all going awry...but I think that the great lack for the Seahawks was execution not plan.
There were a lot of key dropped passes by the Hawks, and badly timed penalties. And in the end going 5 of 17 on 3rd down conversions will kill a team.
