We have not really seen Holloway carry much. It could be that he is doing a lot of grunt work in the tight?
I put up a run-down of his first half in Adelaide somewhere around here.
He's doing the "settler" runs inside 22 and midfield for kick clearances.
He's getting to a few rucks, but not being required to shift bodies (which isn't his fault if the opposition aren't trying to contest ball).
He's winning some lineouts when the hooker isn't getting picked off.
He's not making many tackles because the opposition aren't running into his channel.
Is he ripping it up and destroying fluffybunnys? Not exactly. But then it is a totally different scenario to what was required at the Tahs.
Should he continue at 6? Well I guess incumbency in a winning team is hard to mess with.
