An All-American defensive tackle at Penn State in the late 1970s, Millen went on to enjoy a long NFL career with Raiders, Redskins and 49ers. After that, he began a career as an NFL color analyst. From there he went into management, serving as president of the Detroit Lions from 2000-2008.
Now he's back in college football, this time as an analyst. He will be calling games for ESPN this fall.
We caught up with Millen at Big Ten Media Days here Monday.
