We spoke with John Sigler of Saints Wire to give us a rundown on what we can expect from new Bears defensive coordinator Dennis Allen.

The reason: he was Johnson once. Allen, the Bears ’ new defensive coordinator, was a 39-year-old first-time head coach when the Raiders started their 2012 regular season. Johnson will be 39 when the Bears play their first game with him as their head coach.

In his initial media scrum as a Bears coach, Allen described the type of defense he plans to bring to Chicago, which brings back similarities to defenses that have been well known through Bears history.
