He's 24 next year, and has played 35 NRL games. Twenty one of those came in 2009 (the year he turned 19) for the wooden spooners.
Has not played first grade since 2011 (when he played eight games for the Cowboys, winning half of them).
Interestingly, he has played mostly at centre, as well as in the halves. The fact he's played centre means he must defend well (at least for a halfback).
His breakdown of starting positions is thus:
Fullback: 1 start (0 wins)
Centre: 17 starts (4 wins)
Halves: 8 starts (3 wins)
Bench: 9 starts (3 wins)
Factoids by year:
2008: Turned 18, played one game (a loss) off the bench for the Roosters. Coached by Fittler.
2009: Coached by Fittler. One game at fullback, 10 games at centre, five games at five eighth, five off the bench. Wooden spooners.
2010: Coached by Brian Smith. Four games at centre, one off the bench. Interestingly Smith didn't use him in the halves, and didn't retain him (for whatever reason). The Roosters were very strong that year, making the grand final, however only won two from five with Jones in the team, and conceded 30 points twice and 60 points once while he played centre. So maybe he is a shit defender after all.
2011: Coached by Neil Henry. Two games off the bench, three games at centre, three games at halfback. What's interesting here is two wins from three games at halfback (actually left half) while Thurston was out injured.
2012: Contracted to the Cowboys but did not play any first grade.
2013: Contracted to the Roosters but did not play any first grade.
Here's an article about him from 2011, including quotes by Neil Henry and Arthur Beetson:
