re: Based on similarities with OSU 2018, LSU's defensive problems are probably scheme-related

"New coaches can fix that by either finding new ways to teach the players what their assignments are or by dumbing down the scheme so that their players can better understand their assignments."

I was saying something very similar with different terminology. Either the scheme/coaching (they are inter-related most of the time) is not up to par or there is a lack of talent. (which I would find to be very unlikely)
