They spent the next hour in the interview room. One of the topics was on amateur great and Augusta National co-founder Bobby Jones. Player, who won nine majors, said he felt a player needed to win at least six majors to be considered great.
Nicklaus spoke next on Jones. He said he agreed with everything Player had to say, except that someone needed 10 majors to be considered a great player.
The banter never ends.
