I agree with your sentiment. We need speed in our pack. But geeze I reckon Arthur is as slow as a wet week. Everything he does is at snails pace.I'm not saying picked OVER him. At all. I've said a few times, a better mix of forwards. For example:
Caleb or Arthur lock (or even Caleb in the 12).
Jake 8 or bench (but don't then include all of Sipley, Brown, Tevaga, Taukeiaho, Lodge - and the other logs) - mix it up.
Every team needs a log or two. I shouldn't even use the term log, I should probably say lumbering power (post contact metre) type forward(s).
