I didn't quite understand what you mean.
In the world of cricket , even if we are unfamiliar with a cricketer , cricinfo has all the stats to show whether he's a good player or not . In soccer , except for the forwards who can be categorised good/bad by their goals/games ratio , how do we recognize the good midfielders , defenders ?? And what is the site that tracks any such statistic if a criteria did exist for them ??
