The Ravens are hopeful that the addition of quarterbacks coach Jim Caldwell will provide a boost to Flacco.
Flacco passed for 3,610 yards, 20 touchdowns and 12 interceptions last season.
“Joe and Jim have already spoken a bunch of times,” Harbaugh said. “I’ve talked to Joe and I’ve talked to Jim and I think they’re hitting it off really well. Jim is really spending his time right now learning the offense and contributing to the offense.
“Jim is a big part of rebuilding our offense too. The No. 1 thing he’s going to bring to the table, I think is a great record of teaching fundamentals to the quarterback and teaching some of the nuances that over the course of 30 years of coaching he’s learned. That’s going to help Joe a lot.”
LEARNING FROM REID: Before Harbaugh was hired by the Raves, he was the Philadelphia Eagles’ longtime special-teams coordinator working for coach Andy Reid.
Now, Harbaugh’s the only coach in the NFL to win at least one playoff game over the past four seasons as the Ravens have reached the AFC championship game twice.
“I sure think that he’s done a fine job and he’ll continue to do that,” said Reid, adding that he speaks often with his former assistant.. “He’s wired right. He’s got Ozzie [Newsome] who’s been stable in his position and done very well there. He’s got an owner that he has a good relationship with.
“John is a relentless worker and a pretty smart guy on top of all that. He gets along with people. He knows when you push the players, when to back off. He’s got veteran players that believe in him. He’s able to make people around him better.”
