I am in 3 RT leagues. The 3 teams in those leagues with Pedro, had an average record of 92-68. The 3 teams with AS-Rod averaged 80-80.

Perhaps it's too small a group. Perhaps it's coincidental. Or perhaps, much like real baseball; pitching wins.

The Pedros/Pryors of the world affect every batter they face. A-rod has an effect in one-ninth of his teams total at-bats. Against the great pitchers those results are diminished.

For historical reference see Sandy Koufax or Gibson v. Yankees
