I mean it depends entirely on what basis you want to rank.
The weighting that you give to ceiling, reliability, scoring ranges, hurt factor, likelihood to lose cash, expected score, role certainty, value and what not can all move the players massively.
If reliability is important than Sidey and Martin will move way up. Is explosive upside is your goal then I think Heeney, Butters and Thomas probably move up, and perhaps Martin in the right role.
Dunkley has the hurt factor though which no one else does, he's your textbook "I'd rather be right and have him than be wrong and not have him" pick. If he fails, everyone fails and you've got the head start of having expected it, if he doesn't, your season is over. I don't like Dunkley as a pick but over 50% of my competition does and thus I have to take him because while I don't like him I can absolutely see why others do and I've been wrong enough times to plan around it being not just possible but probable
I'd probably flip Heeney and Butters in your list, Heeney much more role certainty given the lack of competition. I'd have Martin in 2nd right now but for the cash difference and needing another game to confirm his role as best I can. I think I have Sidey ahead of Treloar and Bailey just because of his durability record but, honestly, the variances at this point are so minimal.
