Listen, Dlaw has been really good this season overall.
But what was he doing on QB contain today?
He is a veteran. He has to know better. He has to contain better.
He needs to fix that
On the plays fans are getting mad about he's being left in no man's land with the quarterback able to either hand off or keep the ball. The design of the play is to block down to the left and leave the end up block so that he has to choose whether to tackle the running back or the quarterback. If he goes for the running back, the quarterback pulls the ball out and takes off. If he goes for the quarterback, the QB hands off and the running back has all kinds of room to run to that side of the field.
That's how the play is designed, to put pressure on the end because he's got to essentially stop two players. The only thing you can hope for as an end in that situation is that you fake out the quarterback. He tried that on Fields' last run. Lawrence dipped toward the running back then bent back to Fields, but Fields is a tough runner to take down when you don't hit him full force.
