I have no idea why he wasn't selected,I know he is a left footer and mainly plays on the left,maybe(?)that had something to do with it?
Talau was a half as a junior,but probably asking a lot for him to play there after so long as centre/wing.
As to DCE succession plans...I think Bunting or Arthur are probably the guys on that right side for now.
Dowell in Ball and particularly local jr Davies in Matthews are further down the track.
Davies is one to watch,solid build,takes on the line and quick,good vision and passing game,good defense and kicking game,he is a serious prospect.Alexander plays more on the left but Davies has probably outshone him this year.
For me ,I would have had Humphreys at 7 and Talau at centre with Vaega on the wing,but that is just my two cents worth.
