Speaker over Mays, .345 -vs- .302 , most lifetime doubles (792) means Speaker had as much power as Mays, as good or better defensively, speed about equal, the Grey Eagle just never gets his due.
I can live with Brett at third. And second base is debatable. My lineup has 4 left handed hitters, then 4 right handers, so that's a weakness.
But, Speaker was the best centerfielder of all time.
