What size would you make the league in order to have teams only play each other twice a season? If it's a 16-team league, that means only 30 league games for each club, so only 15 home games, which means a reduction in revenue (in addition to the hit clubs would already be taking by accepting fewer home games against the OF). I don't really see how putting Falkirk and Dunfermline in would mean increased crowds, when those games would effectively be replacing games against Rangers and Celtic.
I really don't get the idea of actively asking for a league that has more "dead" games. Why is that preferable to exciting, important games where there's something to play for? I'd be amazed if this increase in meaningless games didn't also bring with it a downturn in attendances. What we currently have, with some genuine end-of-season excitement to finish the season, is surely miles better for spectators? Maybe I'm on my own here but I'd much rather see a crucial game with a big crowd and a lot to play for, than an end-of-season kick-about where teams experiment with tactics and youngsters in what is basically a pre-season friendly.
