Summer football
Less teams - around 12 top clubs divided evenly into populated areas, ie 1 from Fife, 1 Ayrshire , 2 Lanarkshire, 2 from Edinburgh, 3/4 from Greater Glasgow etc..... Try and distribute it that each team can reasonably expect around 20k at a game. Imagine every stadium in Scotland to be like Easter Road and Tynecastle every week instead of 60K at Celtic park and 2k at Livingston.
Safe standing
No prize money and all TV money distributed evenly. Giving the most successful teams more money is totally counter productive to competition.
Improve matchday experience, better food, stadiums, facilities
1 transfer window to be complete before the season starts
Loan system scrapped or at least limiting it (3 under 21's and 1 over 21yrs old)
SFA/SPL to be made up of independent personnel who's sole goal is to grow the game/league. If they are not doing this they should be moved on.
I'd love a draft system but I think it would be too difficult to apply in football.
