Exactly. Izzy came in never having played rugby. In addition, Izzy struggled to adapt to AFL. Hunt has played Australian schoolboys in something like 2003, easily adapted to Top 14 Rugby 7 years later than adapted well to AFL where his biggest constraint has been injuries.
And with regard to the previous comments that Hunt isn't an elite rugby player, he is elite in skill level. Tactically he might take some time but his handling skills will likely be superior to most players here, thus improving that for us.
