I think she was a fine tennis player, but everyone is in the pros. If you can't produce it, then it doesn't count. That's why it infuriates me when players (Serena comes to mind) repeatedly explain losses by saying "I shouldn't have lost that match (implying they're a better player than the person across the net) but I just wasnt' able to hit my shots today." Hitting your shots is the name of the game.
