At the NFL owners meetings on Tuesday, Harbaugh didn't shoot down a report that Jernigan could be traded.
"Trade talks always go on," Harbaugh said. "People are interested in Timmy because I’m sure they feel like, with our defensive line situation -- we have a lot of good, young players –- that he might be available. So people are going to ask about him."
Mike Lombardi, a former NFL personnel executive who worked with Ravens general manager Ozzie Newsome in Cleveland, said last week on "The Ringer NFL Show" that he hears the Ravens are "talking about moving Jernigan."
This would be a preemptive move, because it's likely Jernigan's last year in Baltimore. Jernigan is a free agent at the end of the season, and it's unlikely the Ravens will spend big money on the defensive line again after making Brandon Williams the highest-paid nose tackle.
Baltimore's interior of the defensive line is also one of its deepest positions. The Ravens return promising second-year player Michael Pierce along with recent draft picks Carl Davis and Willie Henry.
But it wouldn't make sense for Baltimore to trade away Jernigan for anything less than a fourth-round pick. The Ravens probably would get a fifth- or sixth-round compensatory pick in 2019 when he signs elsewhere.
Plus, if the Ravens keep Jernigan, they know they're getting a motivated player in a contract year.
"To me, Timmy is going to have the best year of his career, without question," Harbaugh said. "I know how passionate he is, I know how much he wants to be great."
The Ravens, though, are apparently listening to offers. Baltimore wants to add more draft picks this year, especially with so many holes remaining on the roster. The Ravens have seven picks in the 2017 draft, which is their fewest in seven years.
"Everybody is up for trade," Harbaugh said. "I’m sure that if the Ravens got enough, they’d trade me in a second. Might not take much right now if people are looking."
