To the Tennis Channel list of course a few chosen real experts, like John Barrett or Bud Collins, contributed to. That older players like Laver, Tilden or Rosewall got this many votes, is an indication of it. But nobody knows, how many people and who voted. I think, over 30 or 50 people voted, including many marketing and business people and most of recent business. Its one of my main critical pounts of this voting, that they never gave away an open list of all voters.
The other systematic critical point i have, is the merging of men and women. This is, as pointed out here, idiotic. In my mind, the biggest mistake was the Nr. 30 or what place of Helen Wills.
