I believe the Ravens QB Joe Flacco is coming off season surgery and basically got NO training camp... and their interior OL had great depth, but then pre-season injuries (and a retirement) hit and took that away... they still got some good talent there, but not nearly as much as they once did.
Ravens offense has known for playing a lot of small ball with a lot of running and dump offs and then going for it all with some home run deep ball shots mixed it and they got two speed WRs.
So the deep speed is a negative for the Packers, but since they're struggling with the passing game in general, that's a good thing.
As a RB and TE are clearly leading with the most catches and they're averaging less than 7 yards per catch with those. Even in 2015, when everyone was complaining about TE Rodgers not being able to get deep, and short yardage only guy, he averaged 8.8 yards per catch.
So the Ravens poor passing game gives the Packers a chance... but the Ravens great defense might take that chance away.
