Second half of the season, yeah it's pretty damn weak. Overall Strength-of-Schedule is probably pretty tough, due to the brutal first half of the season. Plus when they did play a playoff team in the streak, they manhandled them on the road. I personally don't really view it as super important because I sort of feel like The Ravens aren't as good a team as their schedule implies, but I'll take the win. Don't want to go back into New England in the playoffs.
The reason Atlanta gets hit with questions all the time is good teams are supposed to beat up on bad teams and play consistently throughout most of the season. Atlanta seems to squeak out wins against bad teams, and have yet to really dominate a team in SF/NE/HOU fashion aside from this last week against The Giants. I'd say they're behind the Broncos and Packers as far as a rank is concerned, as I'm sure both of those teams could beat them if they were to play.
