Your photo seems to go well with my description of Darrell Waltrip
regarding the cars not being able to drive forward on the grass after crushing the front end inward,
I think it must be the front splitter digging into the grass, I can see Jr. having problems after hitting the wall,
but Chase Elliott only hit the grass with the splitter and still got stuck. granted a lot of body damage, he still should have been able to back up.
