Lillyman may seem like a small prop but he's similar in size to O'Meely. He's also the Warriors strongest player in the gym apparently which is saying something for a guy that's 5'11 and just over 100kgs, got a feeling Brown wouldn't be too far behind though.
A one year extension is fine by me, it should put an edge on his game as in he'll be constantly playing to impress for a contract whether it's here or elsewhere. I reckon we'll see some good footy from him from here on in IF he's playing prop and given the depth we have in the second row, prop is his most likely position.
