In a switch that could further strain the relationship between the franchises, New England Patriots wide receivers coach Brian Daboll has left the team to accept a position on the staff of New York Jets head coach Eric Mangini.
Daboll will work under Jets offensive coordinator Brian Schottenheimer, but his role has yet to be determined.
A native of Ontario, Canada, Daboll has been in the NFL since 2000, when he joined coach Bill Belichick's staff in New England as a defensive assistant. He was recommended to Belichick by close friend Nick Saban after having worked on the Michigan State staff for two seasons.
In 2002, Daboll was promoted to wide receivers coach, a position he held for the past five seasons. New York already has a wide receivers coach in Noel Mazzone, so Daboll, who drew praise from Belichick last season for his part in working with a revamped Patriots wide receiver corps, might function more as an assistant head coach.
Daboll was responsible for areas of the passing game and for coordinating many of New England's personnel packages on offense.
The move obviously reunites Daboll and Mangini, who worked on the New England staff together for six seasons.
Before joining Saban's staff at Michigan State in 1998, Daboll worked one season at William and Mary.
