I'd idealy see the ten teams re-join the SFL. 16 team Division 1, 16 team Division 2, 16 team Division 3 then a Highland League and Lowland League below with a pyramid system for entry to Division 3. This would mean we would need 8 more teams to join Division 3. 4 from the HL and 4 from the Lowland junior leagues to join Division 3. Rangers and Celtic can apply to join straight to Division 1 with the former SPL teams, but they have to sign up to the new league rules which means all potential sponsor and TV revenue must be split between Division 1 teams evenly. Also, no matter what league your in, terracing is allowed. No silly stadia rules that will get teams into debt building them.
Far too sensible a suggestion for it ever to happen CC.
