Lendl has been instrumental, that has been obvious. And it´s good for the excitement of the game that Muzza managed to get over the bump in the road. Still, I can´t help but wonder what the result would have been if Lendl had been the trainer of Djokovic instead. That would have probably been the scariest and most ruthless player-coach duo of all time.
Arguably the biggest reason why the Lendl-Murray duo has been such a success is because Lendl was in a similar situation mentally as Murray was when they started and Lendl had managed to turn it around.
