One of the biggest tennis myths floating around is that McEnroe choked away the 1984 RG final. He has repeated that myth several times himself, not least in his autobiography. However he despised Lendl and didn't want to give him any credit (until recently he even refused to admit that they had a rivalry), and he hasn't re-watched the match at all since playing in it. Many journalists who wrongly labelled it as one of the biggest chokes of all time, admitted that they hadn't even seen the match in full either.
It was a fantastic, high quality match with a lot of drama. Definitely one of the best quality slam finals of the open era. McEnroe didn't play that badly in the sets that he lost, but Lendl was brilliant and began to pass him mercilessly. Lendl won that match more than Mac lost it without a doubt.
