From the article:

The man whom linebackers coach Jeff Choate has taken to calling “Coach D.J.” has become a fixture at Texas practices because he still carries the same emotional investment in the team’s success that he did as a rangy, soft-spoken freshman linebacker who arrived from Waco more than 20 years ago.

It’s not rare to see Johnson huddled up with star backer Jaylan Ford discussing techniques or comparing notes with fellow Hall of Honor member and former UT teammate Michael Huff.

The winner of the 2004 Butkus Award and Nagurski Trophy — the line forms behind him and Tommy Nobis as the greatest backers to play here — is a constant presence around the program, and his work doesn’t stop on the practice field. He can often be spotted in the film room, usually with young players whose main priority is turning in a huge season and eventually walking the path he paved from here to the NFL.

"I like to stay involved, especially with the linebackers,” Johnson said. “I also try to make myself available for (pass) rushers and the other defensive guys. It’s a volunteer role, but it’s mostly geared toward helping these young linebackers on and off the field.”
