Agree - a win against Preston and draw against Oakleigh would be a good outcome. If we then send our best players to Fiji, then we should win the remaining 3 matches (Bula, PNG Hekari, Tahiti United). That would lock in second spot behind Auckland prior to the Leaders Group finals series kicking off in early May.
The question here is how many points can we accumulate from the Preston, Oakleigh, St Albans, and Melbourne City matches. After that, the focus will move exclusively to the OFC Pro League. To be honest, we need maximum points from the St Albans and Melbourne City fixtures to ensure we can remain in the top 4 by the end of May.
With the above in mind, that will mean matches in May against Heidelberg, George Cross, Avondale, and a possible Dockerty Cup match will all be played against our weakest Starting XI. I cannot see South winning more than 4 points in those 3 aforementioned NPL fixtures. We would need a favourable Dockerty Cup draw in order to avoid playing senior players in that cup match.
