This is his 4th year at the club, hopefully he goes without any injuries this year and plays all 22 games. Seems to be a bit prone, osteopubis in 2007 and lost the last 8 games in 2009 due to injury. Seems to have the body weight at 78Kg.
I think he is developing fine. I'd hope he continues to develop into an accomplished mid fielder. I think his marks and tackles are OK. I'd hope he gets more than 20 possessions but more importantly we start seeing them being good possessions.
I wouldn't consider this year a make or break unless he gets injured which might kill his career as he could be just too prone.
