Why do a lot of people still say that the Ravens win games with their defense?

I'm a Saint fan and I watched that entire game. Ray Rice was their entire offense, man. lol Defense played good enough to hold the Saints under 30 points, which no team had done 5 weeks prior to that game. I very much think the heart and soul of that team is still on defense. Plus, they only suck on the 2-min drill, it seems. Schaub was in 2 minute mode forever it seemed. Brees destroyed them in the last 2 minutes of the half. They need to clean that up. Overall, I think they are a very good team that can win in alot of different ways. They should go far in the playoffs.
