We are all a bit confused by it, but essentially the views are, in terms of coverage:
Faf: Scrumhalf, flyhalf
Reinach: Scrumhalf
Williams: Scrumhalf, wing (not that this is a position where we have a shortage
Hendrikse: Scrumhalf
So basically a view of having a versatile squad... but realistically the coaches couldn't decide who to cut here so they decided to go with a versatility argument. I don't think we have a very clear view of who our first and second choice scrumhalf is.
On flyhalf, sounds a lot like Pollard is going to be fit enough to potentially play a warm up game, but they weren't sure about his match readyness and have excluded him. My take is, as soon as any of our players get injured and have to return, Pollard will be into replace them. Even if it is one of our props or hookers.
