So, what's a 'Jack' linebacker?

Jimari Butler entered the transfer portal after Rhule was named the head coach at Nebraska, but two days later, after a talk with Rhule, he decided to stay.

Will, Mike and Sam are terms I’ve heard for linebackers, ‘Jack’ is a new one on me.

Under McBride wasn’t there a hybrid linebacker who could drop into coverage, or add pass rush? They called it something else though, not Jack.

I had to look it up. In a 3-4 defense, the weak-side linebacker can become an edge rusher or drop back in coverage. Why this is called “jack” I don’t know but the name appears to have originated at Auburn.

Little known facts known by few - Barney Fife’s favorite book.


There’s also a Ted linebacker, a second middle linebacker.
