***************************************
For OOTP present-day I suggest the following:

AAA - no limit. teams will carry 25 typically, but will have room for rehab assignments without having to shift players. one other advantage is when roster expansion occurs in September the AI won't try to fill up AAA rosters, which it will do if you have a limit.

AA - 30

A - 30

SS A - 30

Rookie - no limit

Summer - no limit
