At this point, I agree, though just think - the defense was missing Woods, Gregory and Irving and still had 6 sacks, the oh-so-fantastic ODB had only 4 catches for 51 yards and NO touchdowns. With Irving and the others back, who's to say the Cowboys can't consistently hold teams under 20 pts? There were 9 teams last year that held teams to 20 pts or less for the season, it's not like it's near impossible to do.
I have hopes that Williams and Looney can learn each others' tendencies and play better, Zeke's still averaging 4.6 yards a carry, despite having few holes to run through. Penalties can be cleaned up, too, if they work at it.
Would be better to increase the scoring, but at least there's reason to believe it can happen.
