Most of the discussions seem to put McEnroe in a slightly higher plane than that of Lendl. In their career record Ivand Lendl has a 21-15 lead over McEnroe with Lendl having more titles. While i agree in terms of natural game and offcourt tantrums ("You cannot be Serious") McEnroe is more reachable and appealing to fans but in terms of sheer gamesmanship and winning Ivan Lendl is no pushover either if not better. My first window to tennis came when i watched French Open final with Ivan Lendl playing Matts Wilander and ever since i got addicted to tennis though never got a chance to play it until last few years. I never kinda felt the same when watching Mcenroe.
