"Jim played successfully in the NFL for a long time," Ravens coach John Harbaugh told the team's website (www.baltimoreravens.com).

Zorn was a quarterback with the Seattle Seahawks from 1976 to 1987, throwing for more than 20,000 yards.

He had a 12-20 record in two seasons as Redskins coach after serving as a quarterbacks coach in the NFL for 11 years. He replaces Hue Jackson, who became the Oakland Raiders' offensive coordinator last week.
