Just before kickoff I leaned over to Ramsrule and mentioned that I was really looking forward to watching the play of our DB's, trying to figure out why it seemed receivers could get not just open but downfield by themselves. And that DID happen, but very few times... easily explained by blown coverage which happens to every team every game.
What I actually saw was great coverage... even some of the 'big plays' Seattle made it took either incredibly great passes or lots of luck to complete, they were defended WELL And that on the short, mid, and long routes.
