Kirk Herbstreit, the former Ohio State QB and current ESPN college football analyst, called Jackson the GOAT (Greatest of All Time) in a social media post Saturday.
Jackson first joined ABC Sports in 1966, and while he would go on to complete an illustrious career where he became the preeminent voice in college football, it was not where he started.
He also called Woody Hayes' infamous last game in 1978, the Gator Bowl between Clemson and the Buckeyes. If there was a big game being played on ABC, Keith Jackson's voice would likely be behind the microphone. Can close my eyes and think of so many of his special calls.
He is credited with nicknaming the Rose Bowl, "The Granddaddy of Them All" and Michigan Stadium as the "Big House".

Rest in peace, Keith Jackson, and thanks for all of the memories.
"'We, too, are saddened to hear of (Jackson's passing)", the University of MI tweeted on its official athletics feed.
The National Sportswriters and Sportscasters Association named him the National Sportscaster of the Year five times, among other honors. Jackson also called college basketball games with Dick Vitale.
Prior to his career in the media, Jackson spent four years in the U.S. marines before enrolling at Washington State University, where he graduated with a degree in speech communications.
Jackson will forever be remembered and dearly missed.
