80’s Leagues all full

All leagues are full - thanks everybody for all of your quick attention!

Never played the 80's before. I notice all the closers are rated a "N". How does the "endurance rating" factor into a save opportunity? If the pitcher in the game has a Closer Endurance rating of "N", then he immediately loses his effectiveness.

The closer rule is not used in the 80's. Only the 90's game uses the closer rule.
