Tale of the tape

Wins added is how many extra games a player’s teams won because they had him and not a replacement-level player, the kind of fill-in any team can find. In one season, 2 is a solid regular, 5 is an All-Star and 8 or more is an MVP-level year. Score is the average of the career total and the best seven seasons.
