You should be careful to note the section in the league constitution noting age limits in the minor leagues. The limits have been relaxed since last year, but they are still in place. This was put in place to reflect the limits on minor league service time at each level in real life. Since we do not have easy access to this data, age is used as a comparable replacement instead.
This takes effect this off-season. Please plan accordingly with your amateur draft.
If you have any questions, please ask.
