The only way I'd trade Preuss was if the club made a play for Bailey Williams via live trading from his resultant currency.
I.e we got a early second rounder or a 2019 first from say Geelong and were able to package it for a live trade for Williams as he's available in the 12-20 range.
I think he's extremely unique, he's kicked some massive bags in junior footy, but is also genuinely elite ruck prospect athletically.
He's a better version of Paddy Ryder imo.
I would then be prepared to carry Goldstein to retirement with Xerri and Williams as developing rucks.
Live trading completely changes the game, being able to align needs with best available.
We're essentially trading a ruck for a ruck, but one that cashes in on the value of a developed one, for one that needs a few years, with probably a higher ceiling.
