In both case, the players have difficulties to execute correctly their shot. But in the second case, they have also some difficulties with their game plan, which is more demanding.
Overall the player who win the most when he plays the worst is the one who has the greatest margin against his opponent.
Well yes but if the opponent gets hot they get blown off court.
I still think that players that are balanced between defense and offense like Federer and Borg (along with having excellent serves) are the best in this category.
