On page 45:
"Last spring Nicklaus joined Doak to address the media at the site of Sebonack Golf Club, a course scheduled to open soon on the eastern tip of Long Island. Doak (ironically enough, a Pete Dye disciple) is one of the few architects to team with Nicklaus since his early days of collaboration with Dye and Muirhead. Doak's scholarly mind and Nicklaus' I-did-it-my-way approach stood in clear contrast as the two architects spoke. Discussing Sebonack and other projects, Nicklaus painted himself as a man who designs in a historical vacuum, using his own high-quality standards and his client's needs as his only guidance.
'The definition of a good golf course is one that serves its intended use of the owner,' Nicklaus maintains, with 'intended use' ranging from player-friendly, sales-inducing real estate courses to golf-for-golf's-sake venues capable of hosting a professional tour event."
On page 83, later in the article is probably the quote you refer to:
"In Doak, Nicklaus recognizes a previous incarnation of himself--the Jack who didn't always try to meet everyone's needs. 'Tom still builds for his own ego, which is all right,' he says, reiterating that in no way does he wish to knock or admonish Doak. 'I built a lot for my own ego when I first started, too. But pretty soon you temper what you do to fit what the owner wants. I'm not criticizing him by any means on this. He's still young in the game.'"
"At Sebonack, with the strong-willed Doak as a partner, Nicklaus most certainly will not be designing eveything on his own. Some creative clashes over design decisions are likely, though the landscape will dictate much. For different reasons, each architect will be fully aware how eagerly history waits to judge the result of their collaboration."
