There are always a lot of questions about this rule so here is how it works:
Here is the NA rule as it will stand for this season.
NA Rule: All standard leagues will continue to utilize 3 NA slots for the purpose of stashing talented players while still maintaining a competitive and fair balanced active roster. A team may only carry 3 NA players in these slots and must be in compliance by the start of the regular MLB season (Thursday,March 29th). Any NA player listed on your active roster on March 29th at the start of the first MLB game exceeding 3 will be immediately removed by the commissioner to the waiver wire. Please read NA exceptions below.
1. Any player, regardless of age, free agent or prospect, can be placed on the NA slot meaning as long as Yahoo has given them an NA designation the only way they can be on their roster is in the NA slot. The only exception being with any player suspended by the MLB must remain on your active roster.
2. Teams will be allowed to carry one NA player on their active roster during the season as long as the player started the season in the MLB and was sent down to the minors at some point during the season.
1. Outside of the start of the MLB season, should a player become NA for any reason besides suspension, that GM will have 7 days to either make room in their NA slots via dropping someone or via trade before punishment will be enforced.
First Violation: Immediately removal of NA player by commissioner from the offending GMs roster.
Second Violation: Immediately removal of NA player by commissioner from offending GMs roster plus the benching of the entire teams roster for the Saturday following the infraction.
Third Violation: Immediate replacement in the league and possible removal from the network pending board review.
In essence the NA rule is the exact same as last season. Changes that occurred in past years were as follows: we did away with the age and prospect restrictions and opened one active roster spot for players that make their MLB teams but get sent down later. We understand this still may not be perfect but these changes were the overwhelming majority from the survey sent on this topic a couple years ago. If you have any questions please either post below or email your respective league commissioner. Their details are in the “About” tab on this site.
