We knew the Cowboys DT rotation was going to be awful this year. We knew it was awful last year and it got worse this year.
I went back and looked at the Saints rushing game against Dallas and here are some stats. Do what you want with them.
The Saints rushed 39 times for 190 yards for an average of 4.9 yards per rush. Three of those rushes were kneel downs at the end of the game or the rush totals would be 36 for 193 or 5.4 yards per carry.
They rushed 19 times to the left for 115 yards or 6 yards per carry. They rushed up the middle 5 times for 23 yards or 4.6 yards per carry (not including the 3 kneel downs at the end of the game.) They ran 12 times to the right for an average of 4.6 yards.
The longest run was 15 yards. They have 5 runs of 10 yards or more, 4 were to the left. 1 was to the right and that was in the 4th quarter when Dallas had some scrubs in.
Of the 36 rushing attempts only 2 gains 0 or negative yards. There was only 1 negative run of -2 yards and that happened in the 4th quarter. The Saints had only 2 negative plays all day. including a 1 yard sack by Golston.
If does not look significant but If I recall a game last year where Dallas gave up over 200 yards rushing, a large percentage of it was to the left. That seems to be where the problem is.
So while our DTs are pretty awful against the run, I think the problem is bigger than just that. For whatever reason we seem to be more vulnerable on the left side. What I did not look at is who was lined up on the left DE. It seemed like they ran there whether it was Kneeland or Lawrence but I do not have the data for that analysis.
