I have to say I like the current set up.
If you take the points away after 23 rounds there is no point playing for the last few. You'd get teams resting players when they know they are in the 8, and for some that would be 5-6 games before the end.
The middle 8s is excellent from an every minute matters point of view.
There is an issue with both from a sponsorship/season ticket point of view but in a lot of ways that is down to the marketeers to be more creative. It probably hurts a team like us more where we have less supporters so a Thursday game hurts us more when a percentage can't attend so it would be good to resolve that issue.
Unfortunately, the best way to resolve the season ticket/sponsorship issue of not knowing who will play when, is to bring franchising back. It guarantees the fixtures for everyone for this season all the way to the end, and as long as they are financially stable guarantees the next 5 years as well.
If we stay with promotion I'd stay with middle 8s, but just market the up coming teams more than talk about the jeopardy of the SL teams.
The top 8 could easily be changed but the final positions at round 23 have to count for something. Even if only financial.
