Ferentz, who was a respected assistant during his time with the Ravens, likely would have drawn significant consideration from the team.
"I've got a great job here, and with that being said, I'm sure Baltimore will get a top-notch coach," Ferentz told The Sun. "They have three great people in Eric [DeCosta, director of college scouting], George [Kokinis, director of pro personnel] and Ozzie [Newsome, general manager] and have great ownership in place."
The Ravens, who fired Brian Billick as coach Monday, are in the early stages of their search for his replacement.
Another factor in Ferentz's decision is that his son James, an offensive line prospect, will play at Iowa this fall.
"Not only does it allow me to coach him every day, but it allows me to watch him play every weekend," Ferentz said. "I couldn't do that if I was coaching somewhere else. You can't put a price tag on something like that."
