Jim Harbaugh, Jack Harbaugh

Wrigley Field hosted three World Series games over the weekend, and Chicago celebrities flooded the stands. Bill Murray, Eddie Vedder, Vince Vaughn, John Cusack, John Paul Stephens, Thomas Ian Nicholas, Jim Belushi, Tom Morello and Jordana Brewster were just some of the faces at "The Friendly Confines".

But most of those celebrities sat behind home plate, in one of the first few rows or in luxury boxes. Jim Harbaugh attended Game 5, but the Michigan Wolverines head football coach sat in the outfield with his glove.

Harbaugh showed up at Wrigley with his father, Jack, who moved around the country as an assistant coach at multiple colleges during Jim's youth, and his wife, Sarah. Jack hails from Central Ohio, and is an Indians fan. He attended Game 2 of the World Series in Cleveland.

Jim, who was born in Toledo and went to high school in Ann Arbor, played seven of his 15 NFL seasons with the Bears. Jim has shown Cubs fandom on other occasions. On this night, Jim donned a Cubs hat and Michigan sweatshirt while his father went all Wolverines.

Jim says he has attained foul balls with his bare hands, but he also says, "You got to bring the leather to the game."

Harbaugh made the trip to Chicago one day after the Wolverines knocked off the rival Michigan State Spartans, 32-23, in East Lansing. Michigan hosts Maryland this coming Saturday in Ann Arbor. At 8-0, Michigan is No. 2 in both the AP Poll and Coaches Poll.
