I say Lendl. Firstly his record. One hundred weeks more at No.1, one more major, more major finals. Dominant player of the 1980s. Either began the push to greater professionalism or accelerated it greatly. Fear factor: His cold on-court persona, power, clinical efficiency, willingness to hit an opponent if necessary made him one of the most intimidating opponents of all-time. Secondly, I would argue a mystique grew up around Lendl which really accelerated and flourished after he quit the game. We didn't see him for 15 years - a few interviews only no biography, nothing much. Mc has been highly exposed - DC coaching, TV show, TV commentary, biography, plenty of interviews, seniors tour etc etc He's had a lot to say - a lot of the time. We've had nothing like that from Lendl. Less is more, as they say. Finally, even though Lendl is back coaching one of the game biggest stars we still don't hear much from him. According to an Aussie TV commentator Murray was/is in awe of Lendl and treats him with a "king of reverence." I remember when it was announced that Lendl was going to coach Murray - there was discernible excitement in the tennis world and tennis sites like these. So opinions? Who is the more respected figure in the game? PS I don't discount Mac's great winning year or the Wimby titles, I just think they come up short in winning this debate for the reasons outlined above.
