Absolutely, if you accept the premise behind an analysis in Friday's Wall Street Journal, which ranked 20 big league managers on:
• Their teams' performance in close games, i.e., games tied through six innings
• Their teams' won-loss record relative to its projected record based on runs scored and allowed (the "Pythagorean" projection)
• How players' individual performances improved or declined under various managers, with allowances made for the players' ages
The managers were ranked in each of the three categories, and the ranks were averaged, giving each manager a composite score.
