To analyze a player's net game effectiveness, one should evaluate a combination of statistical metrics such as win-loss ratio, points won on serve and return, unforced errors, and break points converted. Additionally, assessing the player's performance in key moments, such as tie-breaks and critical games, provides insights into their mental toughness and pressure handling. Analyzing court positioning, shot selection, and consistency can further illuminate their strategic strengths and weaknesses. Comparative analysis against opponents' statistics and their own historical performance can reveal patterns and areas for improvement, leading to a well-rounded assessment of net game effectiveness.
