NFL coaching and scouting can be itinerant work.
Matt Malaspina, promoted to college scouting director after eight seasons with the team, previously spent five years with the Seattle Seahawks. Mike Williams, promoted to director of pro personnel, spent the 2009 through 2011 seasons with the St. Louis Rams.
Last offseason, the Seahawks announced Todd Brunner's hiring as an area scout. He had been with the 49ers from 2001 through 2011. The Seahawks in 2010 hired former 49ers general manager Scot McCloughan as a top assistant to their own GM, John Schneider, who previously worked with the 49ers' current GM, Trent Baalke, with the Washington Redskins.
One of the Arizona Cardinals' scouts, Chris Culmer, worked previously for the Seahawks.
Teams usually wait til after the draft to make changes to their scouting department.
The changes San Francisco announced followed Tom Gamble's departure to the Philadelphia Eagles in February. Gamble had been the 49ers' director of player personnel, reporting directly to Baalke. The 49ers promoted Joel Patten to fill Gamble's role. Patten previously was director of college scouting.
