I'd be happy with one of Zac Clarke/Dawson Simpson/Max Gawn. All are young, appear to be able to ruck competitively, and are all 204cm plus.
I'd even trade for two of them if it meant getting rid of the thinking Herpe and a few other bits of dead wood.
Leuenberger would be even better, but thats more hope than reality.
A Richmond mate of mine whose watched quite a few Port games this year is adamant that Trengove's foot skills are suspect. I'm not convinced he's the answer to our problems, the guy doesn't look comfy playing in defense for mine, and might end up as one of those players too short for ruck (197cm) and not enough talent to make it as a KPP. We could probably do worse though...
Carlisle is 192cm and that's a question for mine.....can he play on the gorillas?
