If he was in his prime using today's equipment. In '68 he averaged 276, so if he played today he would hit it about the same distance as Rory McIlroy (currently averaging 310).
Technology has changed dramatically since Nicklaus won the event. On Thursday he was asked how he would have fared if he could use today's equipment in his prime.
"I would probably hit it another 20, 30, 40 yards I suppose," Nicklaus said. "I would obviously hit it further because I mean, good gracious, when I was in my 50s, when I could still hit it a little bit, we were then using the metal woods and using a composite golf ball. And so I found that I was hitting the golf ball further then than I was in my prime. Obviously in my late 50s, I didn't have anywhere near the club head speed I had when I was in my 20s and 30s."
