McEnroe was being generous when he said she would be ranked 700 in the world. In reality she would be outside the top 1,000. Even college level players would have no trouble returning her serve. On top of that she would be one of the slowest players on the men's tour. It's not chauvinist to say that men on average are much faster and have more muscle than women. Even her height would be a tremendous disadvantage on the men's tour. But hey, if she wants to prove all the naysayers wrong, she can play a match against someone ranked 500, but she won't because she knows she would lose.
