This article has a good look at some of the reasoning behind DP being benched.
Some choice quotes from it:
McGahan
- "We have a young group coming together and we are trying to find the best positions"
- "He's had a couple of weeks with Duncan and we will see where he fits."
- "Duncan has been playing well but we're looking for a change this week."
>McGahan said Duncan Paia'aua had not done a great deal wrong and was rather a victim of circumstance, with the coaching staff eager to test the powerful centre pairing while handing Filipo Daugunu the opportunity to start.
So it looks like this is just tinkering with the side. I do like that Thorn kind of flagged the change last week by trying it in the last game rather than just making wholesale changes at the drop of a hat.
