UNIVERSITY PLACE, Wash. (AP) — Hall of Fame broadcaster Bob Robertson, who called Washington State football for more than 50 years, has died at the age of 91. Washington State said Robertson died Sunday at his home. Robertson was inducted into the College Football Hall of Fame in 2004 when he received the Chris Schenkel Award. Robertson served as the lead broadcaster for Washington State football from 1964-2011 — except for three years between 1969 and 1971 — before moving into an analyst role. He retired midway through the 2018 season.
