"I've got all kinds of methods and ways, but I've got to learn who Joe is and what I can help him with," Zorn said. "What I see in watching Joe is that he's got some great, natural talent, and he uses it. I don't know enough about him yet to see where I can help him, but that will come. I haven't even walked in the door yet."
Flacco has started every game in his two-year NFL career and passed for 6,584 yards and 35 touchdowns with 24 interceptions. The Ravens also reached the playoffs in both seasons.
Zorn, who was fired by the Redskins earlier this month, knows a lot about being a quarterback in the NFL. He threw for 21,115 yards and 111 touchdowns with 141 interceptions in 11 seasons with the Seattle Seahawks (1976-84), Green Bay Packers (1985) and Tampa Bay Buccaneers (1987). He then coached the position for 10 seasons with the Detroit Lions (1998-2000) and the Seahawks (1997, 2001-07) and helped quarterbacks such as Charlie Batch and Matt Hasselbeck develop.
"Jim played successfully in the NFL for a long time," Ravens coach John Harbaugh said. "He knows what quarterbacks go through in this league. He has been a quarterbacks coach and a head coach, and he is familiar with our offense. That's a great resume.
"I've gotten to know Jim for the last couple of years, and I have been impressed with him as a person. He's a good, decent man, and he will be an excellent addition to the Ravens. This is an exciting addition to our staff."
