Question: To whom is the deep tone of this retired American sportscaster, who noted the final game of 1978 NCAA Division I-A football season was  the greatest game he'd ever seen, compared?
Sentence (from "Keith Jackson"): Keith Max Jackson (born October 18, 1928) is a retired American sportscaster, known for his career with ABC Sports (1966–2006), his intelligent yet folksy coverage of college football (1952–2006), and his distinctive voice, with its deep cadence and operatic tone considered "like Edward R. Murrow reporting on World War II, the voice of ultimate authority in college football."
Relevant evidence: Yes
