That's a good breakdown, but he didn't mention that the Rams are in an undershift, which they do far less than overshifted line. And as he pointed out, the nickle showed, then backed out. JL is in Mug position and essentially took Donald's spot in the rush. Donald dropped to cover left hook zone. Also, Chris Long from 5-tech slants across 2 gaps and center ends up blocking him, also the guard takes him and that double allows Jl to come free.
