Atlanta Falcons defensive coordinator Jeff Ulbrich will handle play-calling duties, though the process of building a scheme will include lots of collaboration.

The Falcons fired defensive coordinator Jimmy Lake and defensive line coach Jay Rodgers after an underwhelming season in Atlanta. The defense finished 23rd in points allowed and 23rd in total yards, while ranking 31st in total sacks last season.

The Falcons announced the hiring of Jeff Ulbrich as their new defensive coordinator on Saturday night. The team interviewed seven candidates this week following the firing of defensive coordinator Jimmy Lake on Jan. 11 after Lake’s one season with the team.
