Select Minimum & Maximum Years:
 

In creating a Historical League, after choosing to use random players there is a prompt to "Select minimum & maximum years" with two drop down boxes for the selection.

What does this do?

I have reviewed the manual and can not find any reference to this selection.

The earliest and latest years players will be drawn from.

For example, if you set it to 1940 min and 1970 max, you'll never see Babe Ruth. He was way before 1940. Nor would you see Mike Piazza, after 1970.
