Agree with AngusH - Froling, by a country mile! It is not even a contest.
There are really no other contestants that come close.
As for rookies not nominated, Kings have few Deng & Wilson. But if you only played the minutes they have for the season it is a bit hard to be nominated, isn't it?
Jeremy Kendle, a previous SEABL MVP winner got a lot of plaudits in last weekend's game against Sydney Kings and other SEABL guards seem to get reasonable court time (Hooley, Adnam, Grida, Drmic) and none have achieved what Wilson has (MVP & 2 x ROTY) and Deng seems quite good, with the limited time he has played, he's a highlight reel in waiting.
I know there are knockers out there, as there are for all players, but I can't really work out why these two haven't played more.
IMO it looks like they joined the wrong team and I cant help but think they'd be playing useful minutes at a number of other teams and developing.
