It's an interesting observation that the Packers have been more successful running to the right side. The blocking hasn't been that much better on those plays (1.62 yards before contact) than on rushes to the left side (1.37).
I was talking specifically about stretch runs, with the point being they don't run it enough. Because they don't use it much it would not have put much of dent in averages one way or the other, whether I'm right or wrong.
OK, so I went back and looked at the replays for every run play in the Washington and Minnesota games, as identified in the ESPN play-by-play, to log the stretch run results, presented below. I would have done the Bear game too, but I saw enough to satisfy myself on this thesis, with plenty of time spent already on those two games. I'm pretty sure I saw the stretch run work successfully against the Bears, but I'm not absolutely certain.
I define a stretch run as one where the entire O-Line moves laterally in one direction off the snap. If there's back side O-Line seal blocking or pulling around inside seals that's not what I'm talking about. If only a backside TE happens to seal block but the O-Line is on the move laterally, I counted it. There are other runs left or right where the line attacks forward angling left or right, That's not what I'm talking about either. Again, see those Wiliams clips as a point of reference. It's a zone blocking read with the entire O-Line making an initial lateral move in unison off the snap, not specifically designed for the runner to go to the edge, though he might end up there if the opportunity is presented. The runner reads and reacts, one cut and go, to where he sees a crease.
Here are the stretch runs I've identified for those two games:
Minnesota
1st. quarter, 1:28, 1st. and 10, pistol, TEs right and left, hand off
right to Mongomery agaisnt 7 in the box: 16 yards inside the RG
4th. quarter, 6:32, 1st. and 10: it was
right to Williams for 6 yards but called back for holding on Bakhtiari.
4th. quarter, 3:13, 1st. and 10, pistol, TE right, hand off
right to Williams against 6 in the box: 3 yards
Washington
1st. quarter, 2:14, 1st. and 10, pistol, two TEs left, pitch
left to Williams against 7 in the box: 5 yds inside the LT
1st. quarter, 0:52, 1st. and 10, pistol, one TE right, hand off
right to Jones against 6 in the box: 10 yards outside the RT
1st. quarter, 0:09, 1st. and 10, pistol, 4 wide left with Jones who motions to the backfield, no TE, hand off
right to Jones against 6 in the box,: 8 yards inside the RT
[For those who have replay access, check this one out. It is a thing of beauty out of a spread offense.]
3rd. quarter, 15:00, 1st. and 10, pistol, TE left, double slot left, hand off
left to Williams against 7 in the box: -2 yards
Conclusions
The first thing that jumps out at me, which I did not expect, is that it was only run on 1st. and 10. Watch for it on that down and distance going foward. Hopefully the defenses won't.
I see it run 4 times right, 2 time left, in those 2 games.
They run it out of a variety of formations.
The 6 that counted netted 39 yards for 6.5 yds. per carry. Considering they were all 1st. and 10, a running down if there is such a thing anymore, that's pretty impressive.
As for those stats, not especially relevant to my point, I would note a 0.25 differece before contact is something more than chump change. It's half the difference between a 4.0 "average" number and a 4.5 "good" number. Further, how does yards before contact translate to total yards? Is it one-for-one factor? More? Less? Or maybe it's all just a function of having better run blockers on the right side or an in-line TE on the right side more often than on the left.
Again, the plays I've cited are not sufficient to bend the curve on that stat one way or another. Maybe they would if they ran them more.
