The problem I have with stuff like this is it's a report based on an article that takes nothing else into consideration but the number of missed starts a team has. It doesn't look at the positions lost or the players involved. But even more than that, the ESPN article confusingly ignores Campanaro, Elam, Taliaferro, Will Davis, Pitta, Urban and others when they calculated the games missed. The Ravens are above the Packers at #1 just in season ending games missed. So using that to compare teams and their wins-losses doesn't make much sense to me.
You can look at just the position injuries they have and see why the "#14" Ravens are struggling with their injuries more than the more banged up "#1" Packers. Especially considering most of the Ravens loses are coming down to the defense holding teams late.
Loss to Injury by Position (using ProFootball Reference since they correctly assign Pitta and Urban to the injuries):
Packers:
1x Tight End - 1x Defensive End - 2x Linebacker - 3x Wide Receiver - 2x Safety
Ravens:
4x Tight End - 1x Defensive End - 1x Linebacker - 4x Wide Receiver - 3x Safety - 3x Corner Back - 1x Running Back - 1x Defensive Tackle - 1x Offensive Tackle
Wanna know who is doing the math at ESPN.
