Jim Harbaugh is a former Chicago Bear, but that's not the main reason why he'll be rooting for the Monsters of the Midway this fall.

Harbaugh, the current Michigan head coach and former head coach of the San Francisco 49ers, used to coach alongside current Bears assistants Vic Fangio and Ed Donatell in the Bay Area.

Fangio, the Bears' defensive coordiantor, and Donatell, the Bears' defensive backs coach, held those same positions for all four of Harbaugh's seasons leading the Niners.

Harbaugh voiced his support for his former assistants Monday, speaking with CSN's Pat Boyle at the Golf.Give.Gala golf outing in St. Charles.

"I know (the Bears) are going to have a heck of a defense," Harbaugh said. "Because I know they've got Vic Fangio and Ed Donatell and a tremendous coaching staff. So I'll be pulling hard for them."

Harbaugh also was asked about new Bears quarterback Mike Glennon, and you can hear his comments in the video above, as well as comments from Ohio State head coach Urban Meyer on another new Bears quarterback, Mitch Trubisky.
