Seattle deserves some credit for playing capably on offense, taking advantage of some really shoddy tackling and blown coverages by the Saints, but they still gave up 36 points. New Orleans didn't strike me as a strong defensive team at all. I don't think they would have beaten Green Bay or Philadelphia either, especially since they were so depleted at RB.
I like the Bears odds next week. The Bears did lose to Seattle at home early in the season, which is reason enough to find it not likely to happen again. But in that game the Bears went 0 for 12 on 3rd downs, which is pretty close to statistically impossible. Seattle has routinely given up 30+ points in the 2nd half of the season, and the Bears had some big offensive games towards the end of the season, not counting the meaningless game against GB when they had a preseason-style game plan. I think barring fluky turnovers, the Bears win easily. They tackle and defend so much better than New Orleans.
I like Atlanta to win also. Green Bay makes tons of mistakes, and Atlanta rarely makes any. GB drops too many passes, commits too many penalties, and McCarthy is a bad clock manager. If not for the fluky out of bounds on the two-point conversion, or even one of those kicks being made, they could have lost. I don't think they have too much to feel good about after this week.
