Source: Atlanta Falcons book 2nd interview with Jim Harbaugh - ESPN

The Atlanta Falcons are scheduling a second interview with Michigan's Jim Harbaugh for the team's vacant coaching position, a source told ESPN on Saturday, confirming a report.

The date of the second interview is not yet clear. Harbaugh first interviewed with the Falcons on Tuesday — a little more than a week after he led Michigan to its first national championship since the 1997 season.

The 60-year-old Harbaugh has been at Michigan since 2015, where he has gone 86-25, including 12-0 this season despite being suspended twice during the regular season. He has won three straight Big Ten titles with the Wolverines.

Harbaugh has won at every stop he's been a head coach. Before Michigan, he coached the San Francisco 49ers for four seasons with a 44-19-1 record, two NFC West titles, three NFC title game appearances and one Super Bowl appearance, losing to the Baltimore Ravens in Super Bowl XLVII.

He took over a struggling Stanford program in 2007 and finished with a 29-21 record, including a 12-1 mark in 2010 and a 40-12 win over Virginia Tech in the Orange Bowl, the first time the Cardinal had won a BCS bowl game and helping to develop future No. 1 overall pick Andrew Luck.

He started his head coaching career at the University of San Diego, where he went 29-6 and helped develop quarterback Josh Johnson into a future NFL quarterback.

As a player, Harbaugh appeared in 177 games with 140 starts, completing 58.8% of his passes for 26,288 yards, 129 touchdowns and 117 interceptions for the Indianapolis Colts, Chicago Bears, Baltimore Ravens and the then-San Diego Chargers.

Atlanta also had a second interview with former New England Patriots coach Bill Belichick on Friday.
