The drain of players like Newsome is the reason why Aussie teams are consistenly beaten by Kiwis sides. Short squads so if you lose players like Liam Gill you can't cover propertly the absences.
I remember the 2019 Semifinal between Jaguares and Brumbies. The Ponies lost Pocock for the clash and they couldn't replace him properly. The lack of quality subtitutes and good impact players at Super Rugby level is one of the areas where NZ overtakes Straya. And the departures of players like Newsome is the key. He's not a superstar but you need proper backups and I have no doubt that he is
I agree with you completely.
The reality is that we can't pay this player nearly enough to keep them here versus what they can get overseas.
NZ have hundreds of Alex Newsomes so they will always have this level of player available to fill holes in their sides.
