Green Bay Packers center-linebacker Ken Iman (53), falls to the ground at center during a drill as training camp begins on the practice field across from new City Stadium in mid-July 1962. Quarterback John Roach (10) is at right. Press-Gazette archivesI don't know who #23 is, but look at the name taped across the back of his helmet. #23 wasn't in circulation in 1962, and there are only two players on the all-time roster with names ending in -sky, neither of which fit.
I'm guessing that it's Roger Holdinsky, back from West Virginia, who was the Packers' 15th round draft pick that season.
Here's another of the Packers' picks, also bearing his name in masking tape.
Green Bay Packers halfback Jerry Scattini (43), the team's 19th-round draft pick, and another player hit a blocking sled with running backs coach John "Red" Cochran aboard as training camp begins on the practice field across from new City Stadium in mid-July 1962.
