The coach lost the running back to Alabama in college recruiting, but NFL free agency has united them with the Chargers.

Harris, 27, signed a one-year deal with the Chargers earlier this week and said that Harbaugh was a driving force in his decision. "He's the same guy, man," Harris said. "He's always energetic, man. He's always the life of the party, so he's just a good guy to be around, down to earth, and he makes you feel comfortable."

Running back Najee Harris signed with the Los Angeles Chargers on a one-year deal worth up to $9.25 million earlier this week. Harris will now get to play under Chargers coach Jim Harbaugh, an opportunity he sees as a "full circle" moment.
