Nothing surprising about those numbers. The same shit has been going on for years. Opposing offenses never worry about 3rd and long as they can always hit someone over the middle to get the 1st. If they are short on 3rd, they will go for it on 4th and get it nearly every time.
I will say they have been playing a bit better, but far from what I would call acceptable. They will really have to dial things in for this final stretch or there will be no playoff spot for the Pack. Maybe if they make more key plays like their last snap against the Browns in OT.
