Tips for running entire league?
 

I'm planning on taking control of all 31 NHL teams, I've attempted this before, but haven't had the best knowledge of how the game runs. Now being used to the game, I was wondering how often I should have the AI control the team to keep the realistic aspect of the game. I would love other tips to try to keep the game as realistic as possible.

Also, a separate question, if I had a 4th line player have a 40-50 point season, do the rating change reflecting from the improvement in numbers? Does the AI recognize this? What are good weights to AI on how much value they see on players from their stats? Thanks, an amazing game
