Man, this keeps going around in circles..
Personally, I think we should now just trust the judgement of the coaching staff. In summary:
1. only 2 hookers - it seems the rules don't differentiate between props and hookers. If 2 front rowers go down, the accentuating circumstances clause kicks in and we can call in a replacement, regardless of how close to kick off it is. In the absolute worst case scenario that we lose a hooker in the warm up then we have a prop who can cover. That would be the case in ANY test match.
2. too many wingers - the squad structure seems designed to have 2 complete starting XVs. The reason for this is the draw. We have 3 games in 10 days, but fortunately the easiest game - Uruguay - is in the middle. So, none of the 'A' XV have to start against Uruguay. The expectation is that the 'A' side will play against Fiji, mostly rest against Uruguay and then play from England onwards. It also means they can train as a XV for the entire tournament, no interruptions.
3. Further, we would expect any injury replacements from 72 hours prior to the Uruguay game onwards to allow for a more conservative squad structure. And there will be injuries, fact.
4. aside from perhaps James Horwill, the players from EVERYONE's preferred match day 23 are in this squad (based on the RC squads). If you think that [insert name of offending player] is a dud selection, refer to point 2.
Bring on the RWC and bring back Bill!
