Wake Forest coach Jim Grobe has named current assistants Brian Knorr and Tim Billings co-defensive coordinators, Grobe told ESPN.com on Monday. The Demon Deacons were scheduled to start spring practices Tuesday, but the unexpected departure of former defensive coordinator Brad Lambert, who left to become the head coach of Charlotte, forced Grobe to reshuffle his staff. Wake Forest now is expected to start practicing Friday. Knorr, who was coaching the receivers, was the inside linebackers coach under Grobe at Ohio University, where he succeeded Grobe as head coach. He also will coach the inside linebackers this year. Billings, who coached the outside linebackers last year, will continue that role. Billings was head coach at Southeast Missouri State (2000-05) and defensive coordinator at Marshall in 1999. Steve Russ will move from linebackers to the secondary. Grobe also has designated Keith Henry, who coached the secondary last year, as the special teams coordinator. Read more: http://sports.espn.go.com/ncf/news/story?id=6218379
