Washington worked under Kurt Schottenheimer last season, under Bob Slowik for a couple seasons before that and has been an assistant defensive backs coach with the team since 1999. He was thought to be a leading candidate to be the secondary coach under new coordinator Jim Bates.
The 35-year-old Baker is the son of University of Wisconsin-La Crosse athletic director Joe Baker Sr.
The younger Baker coached the Saints' secondary the last two seasons, with a primary responsibility being with the safeties. He shared the title of being overall defensive backs coach with Greg Brown. Baker was an assistant secondary coach with the Saints from 2000-02 and a special-teams coach from 2000-01.
With Baker sharing responsibilities with Brown the last two season, it's a possibility he will do the same with Washington.
Before that, he coached linebackers and special teams at the University of Wisconsin during the 1999 Rose Bowl season. He spent the 1994-98 seasons in Jacksonville, first as manager of football operations and then assistant special-teams coach from 1995-98.
Baker was a wide receiver on Princeton's 1989 Ivy League championship team. He graduated with a history degree in 1991.
