A 14 team league will certainly reignite the interest in 1st division football and gives a lot of hope to 1st division fans regarding top flight football and still keeps it competitive.
With 16 -not enough games are played.
18 -wouldn't tally up
20 -would work in theory 38 games but not in practice, we don't have enough quality teams to add 8 and it means the likes of Brechin could win promotion to the SPL the following year which would dilute the quality in the SPL
If I make up some figures, say the SPL put ?2,000,000 in to a pot and all the teams get a cut, making a 20 team league the pot still sits at ?2,000,000 so its less to share.
The same goes with tv rights.
A SPL 2 league cup could be created.
A top 8 bottom 6 split gives hope to the smaller SPL teams of getting in to the top half but 6 and 8 would make more sense considering the smaller teams will have to play more games to get the money in through the gate and the best 6 teams should be involved in cup games for a longer period, it also rests players for international games.
I'm in favor of 14
