Leagues that aren’t listed there are the top ten nations by population (except Romania, which is listed), Norway, Sweden, Belarus and Portugal.
Norway, Sweden and Belarus each have a 16 team division which by my calculations is 30 games.
I think Norway and Sweden have both had a decent variety of winners, don’t know about Belarus. Their European coefficient is shite and they don’t get an EL place now.
Portugal has 18 teams (34 games) and for a country twice the size of Scotland is no more competitive, basically a three way OF.
Other similar ish countries that have a split are above and below us in the rankings, although I don’t think any are quite as uncompetitive.
Evidence is limited but I’d say that there’s some suggestion that fewer games could improve competitiveness in terms of more winners, possibly, but could come at the expense of European places.
Of course, none of the leagues above are starting from where we are. I’d guess that if we wanted a competitive title race we’d have to do something radical and way outside the bounds of currently plausible. Pissing about with numbers of teams won’t change the major weakness in Scottish football.
Having said that, I don’t think it’s particularly broken. Sure it’s shite that it’s hard to win anything but the whole culture, spectacle and experience is very entertaining.
