What have you seen in Ryan Jones that makes you think he'll make it? He's a very quick & strong young man but his natural rugby brain seems lacking from what I've seen of him

Not a great example. Nearly 20 years ago, and a player whose body was f***ed very early into his career

Sculthorpe was 19/20 when he made his debut according to wiki.

This says different.

Biff take the point about freakish guys like sam burgess and andy Farrell, however they are very rare and sam burgess had encountered serious issues with both shoulders by the time he was 19 resulting in surgery and missing 2008 World Cup. Farrell was alright because he had a lower centre of gravity probably due to pie diet mentioned before and at 17 had a backside the size of a small car.

Look at the last guys that slotted quickly into the first team at Leeda from the academy Stevie 'brittle shoulders' Ward and Sutcliffe.
