Film Review: Minnesota's Backside LB in Cover 4
Minnesota’s run defense played pretty well against Northwestern. Mostly utilizing Cover 4 , they were able to maintain numbers advantage inside the box for most of the game. When they did get gashed though, it was mostly because the backside was slow in pursuit. In Cover 4, the LBs, particularly the backside LB, must flow fast. If he reads the play immediately, he can tend to read “cloudy/clear” and shoot off the butt of a pulling OL or beat a zone blocking OL across his face and blow up the play in the backfield. If he can’t do that, he must scrape over the top quickly to get to the playside.
