It's really frustrating too, because our red zone efficiency is very high. The problem is we have way too many drives that go 3 and out.
Our offense definitely needs to improve because we have a good enough defense (granted, with its own flaws) that will keep us in every game. Score more points on offense, limit the turnovers and you will probably win most games.
Hopefully now that the OL is playing better our offense as a whole will improve as well and we'll be able to drive down the field more consistently.
