Frank Gifford seems an odd choice, except that he was a member at Winged Foot. I remember that because an acquaintance of mine had his locker in the G's, between Joe Garagiola and Gifford.
ABC Sports used almost everyone on the U.S. Open that year, including Chris Schenkel, Jim McKay, Keith Jackson, Bill Fleming, Frank Gifford, and Henry Longhurst, one at each hole, plus Byron Nelson as lead analyst. This was before the notion of using McKay and Dave Marr for one segment, then Peter Alliss for the next one.
