managers will have to think twice before promoting
I'd ask the community to think about what that percentage should be. For reference, remember 4/16=25% of teams demote every season, and so a guess of 25% would mean that newly promoted teams were just as likely as the average D1 team to demote. I would posit that the ideal percentage should be higher than that... but how much higher is an open question.. what do you think?
managers will have to think twice before promotingExactly! I've written about it some posts ago, some managers prefer to win the tournament and lose the final match to be promoted.
My impression is that a promotion followed by a demotion brings more money to that team than no promotion/demotion. I might be wrong though.
