In fact, I posted this on another board, but it's also applicable here. It's about how we can be easily misled when we judge the holes in retrospect:
"Now, here's what you will miss:
That's why Gurley didn't just run left. In fact, there are two players there. Rowe has outside contain and is positioned perfectly. McClellin also has set the edge and is positioned well. If you notice, both guys are positioned on the outside shoulder of the offensive player and facing the sidelines. This will allow both guys to shoot up-field and make the tackle if Gurley bounces it too quickly.
Gurley gave Robinson time to take care of McClellin by running into his blockers which allowed him to bounce it outside after stiff-arming Rowe. It seems odd to think about, but Gurley running into his blockers saved this play.
Here's a different angle. This angle will show you were the run was designed to go:
This run was designed to go between #61 Tim Barnes and #68 Jamon Brown. They also had Kendricks come from across the field behind the LOS to try and take out the back-side defender to allow for a cutback lane.
Problem here is that #61 Tim Barnes fails miserably to seal the DT. Him and Brown are both supposed to seal their guys and create a lane for Gurley to the second level. If Gurley gets that seam, as we can all see, this play goes a long way. Barnes gets pushed into the hole and turned. This allows the DT to shutdown the primary running lane and put his body in the cutback lane. Additionally, #69 Cody Wichmann trips over Rob Havenstein (OL on the ground) and fails to block the Patriots LB coming to close the cutback lane.
That puts Gurley in an impossible situation. His primary running lane is closed. His cutback lane is blocked, and the Patriots have set the edge properly to keep him from bouncing. Gurley tries to push his way through between Barnes and Brown. But he cannot. However, doing that allows Robinson to push McClellin out of the play which gives Gurley a 1-on-1 with Rowe outside. He then bounces it.
Basically, you were screaming at Gurley on a play where he made something out of pretty much nothing.
I'll give another example as to how what people think they see often isn't correct:
On this play, people will notice right away from the first picture that Gurley has two choices. He can run right or left. There are two holes initially opened. Gurley chooses to run left and picks up 9 yards after getting skinny through the hole that started to close quite quickly.
Of course, people will look at this play retrospectively and say, "Gurley has bad vision. Look at that gigantic cutback lane on the back-side of the play. He should have chosen to run there."
However, these people show that they misunderstand two key things:
1. LB pursuit angles are often dictated by the path the HB takes in the back-field; and
2. How the blocking scheme is designed on this specific play.
On this play, Jamon Brown is helping with the double team initially and then peels off to block #54 Dont'a Hightower. This is important to know because Hightower is the key to success on this play. If Brown can't block, this play is stuffed for a 3 or 4-yard gain. Because Brown can block him, this play goes for a 9-yard gain.
The question now becomes: What allowed Brown to make the block? The answer is Todd Gurley's vision and patience. Gurley stays centered behind the LOS as long as possible before choosing his path. This holds Hightower in the middle of the field. When Gurley chooses his path, he presses the LOS and hits the hole on the left-side. This is important because it gives Brown an angle to reach Hightower on the second level. That is what allows him to block Hightower.
If Gurley had hit the hole on the right-side, Brown wouldn't have had an angle to reach Hightower at the second level. That would have allowed Hightower and Sheard to fill the hole and stop the play for a short gain."
