Let me preface this with a disclaimer: yes, I know this is a stupid and questionable practice. The Cowboys went 0-4 in the preseason last year, yet finished 12-4 in the regular season. Yes, the preseason is an almost pointless exercise. As are preseason power rankings.
Still, as a Ravens fan, you have to be a little concerned after the team has been hit with injuries and woes along several fronts this offseason. Running back is a big area of concern, though the return of all 5 starting offensive linemen should shore that up nicely.
But there are other areas of concern as well.
