16 teams is the perfect number for Greece. 30 rounds done and dusted like we have now. If you go 14 teams, then by default there must be extra games, which is to say, for whatever reason the sports minister definitely wants play-offs of some kind. There must be more to it than the sports minister wanting this. Not being conspiratorial, just saying that he alone wouldn't be enough to push for and get this. I'd be hiring a private investigator to check his swiss bank account(s).
As for the idea of a title being decided via play-offs, it obviously just feels wrong. We all "get" that the idea is to have less teams that are "weak", but having a title decided just has a bad smell to it and I don't think you can get rid of that. I am kind of surprised the clubs haven't pushed back harder.
