The Minnesota Vikings made their hire of Alan Williams as their defensive coordinator official on Thursday, according to ESPN Twin Cities. Williams had a great interview and the two-week long search for a defensive coordinator came to an end. He replaces Fred Pagac, who is expected to stay with the team in the role of a linebackers coach. According to the piece, it also notes that Mike Singletary is likely to remain in that role as well, though there have been conflicting reports regarding his future with the organization.
Williams spent the last 10 years as defensive backs coach with the Indianapolis Colts, who are in a transition period right now - it's unclear if Williams would have had a job even if he had stayed there. He's got a history with Vikings head coach Leslie Frazier, having coached with him on the Colts, notably in the 2006 Super Bowl season.
On top of that news, the Vikings hired Brendan Daly as the team's defensive line coach. Daly spent the past three seasons with the St. Louis Rams, and before that was with the Vikings.
