I think at this stage, there's not too many premium standouts (aka MID only players getting DEF/FWD status that make them keepers in DEF/FWD) - although it will be handy when rookies get their DPP (Daicos!)
From a quick scan, some semi-relevant players;
ADD DEF:
Zorko $595,400 MID
JPK $506,700 MID
Pendles $492,300 MID
McGrath $464,600 MID
McDonald $372,100 MID
Brayshaw $366,200 MID
McGovern $256,000 FWD
Daicos $193,800 MID
ADD RUC:
Xerri $208,200 FWD
ADD FWD:
Newcombe $261,300 MID
JHF $207,300 MID
Daicos/JHF/Xerri getting DPP is pretty relevant, but obviously not to the discussion above aka premiums.
I can't see any of Bont, Lyons, Merrett, Keays etc getting DPP, the types of players that would definitely be keepers in their position.
From my DEF list above, I have no real interest in JPK/Pendles/McGrath unless they had some midfield injuries and reverted back to their old roles. That being said, JPK/Pendles (and even Zorko) don't seem to be reverting back to midfield roles any time soon at their age. Would also be hesitant to pick Zorko with his body issues (no guarantee he gets DPP anyway)
I don't think it's a factor at this stage (aka Heeney, English and to a lesser extent Hewett, should barely be affected by any DPP additions)
One to look out for around Round 5-6 and assess then IMO.
