As others have mentioned,maybe you should wait until game day,Seebs doesn't name a kid straight up to stop media pressure etc...
As to his dummy half play ...He was named ahead of Tong and Lawton in the pre season,however,his form in the trials was very average and it was clear at the start that he had dropped down the order after actual game time.
Arthur as an NRL player was always going to be ahead of him,Wakeham who has NRL experience was also named ahead of him(this was confusing,but think the club was still looking at him as a 9)
I agree that he should have been kept as a half,but maybe the club thought that was his fastest progression to NRL as a 9 and it just hasn't worked out?
I doubt the club could afford to keep him if his current form continues anyway.
