"There's been some discussion but nothing substantive," said Trace Armstrong, a former NFL player who represents Schottenheimer.
Schottenheimer, 64, is expected to wait until the Ravens are done with the first round of interviews before speaking with them again.
The hiring of Schottenheimer would entail the least amount of risk in replacing Brian Billick.
Schottenheimer has a career record of 200-126-1 (.614 winning percentage) during his time with the Cleveland Browns, Kansas City Chiefs, Washington Redskins and San Diego Chargers, and he has had only two losing years in 20 full seasons as a coach.
He was fired by the Chargers at the end of the 2006 season after the 14-2 team finished with a disappointing loss in the second round of the playoffs.
Schottenheimer said last month that he would not return to coaching unless it was the "right circumstance."
Said Armstrong: "I think Marty has earned the right to be selective given what he's accomplished and where he is at this point in his life. Having said that, I personally feel that Baltimore is a tremendous organization. They have a great front office, great ownership and are in a great market. I think there is some talent on that team."
The biggest knock on Schottenheimer is his struggles in the playoffs, in which he is 5-13. But he brings more experience than any of the candidates interviewed by the Ravens.
Another difference with Schottenheimer is his strict, old-school style. Some league observers say they think Schottenheimer would be a good fit because he brings more discipline.
Armstrong said Schottenheimer's relationships with his teams have never been a negative.
The Ravens don't have to talk to other former players because general manager Ozzie Newsome played under Schottenheimer in Cleveland.
In four full seasons with the Browns, Schottenheimer won 40 games and guided them to two AFC championship game appearances.
Whether it's with the Ravens or another team, Armstrong hinted that Schottenheimer would return to coaching.
Schottenheimer would likely bring recently fired Miami Dolphins head coach Cam Cameron as his offensive coordinator and former Kansas City Chiefs offensive coordinator Mike Solari as his offensive line coach.
Notes -- According to the East Valley Tribune, Terrell Suggs told an Arizona television station that he would love to play for the Cardinals, although no quotation is attributed to the linebacker. Though Suggs is a pending free agent, the Ravens are expected to keep the former Arizona State star with either a franchise tag or a long-term contract. ... There has also been growing speculation that Colts assistant head coach Jim Caldwell - who interviewed with the Ravens eight days ago - might become the next Colts head coach as early as next season if Tony Dungy retires. It stems from a report that Dungy's son Eric has enrolled at a high school in Florida after spending the previous two years at a high school in Indianapolis. ... Tennessee defensive coordinator Jim Schwartz, a Mount St. Joseph graduate, is considered a front-runner for the Washington Redskins' job, according to NBCSports.com.
