Something to bare in mind in defence of Perry.
Perry played over 200 games in the NRL in a 10 year career encompassing state of origin and Australian caps into the bargain. A forward who was lazy would have been easily found out, and so would not have had such an excellent career.
This makes me think that his current lack of fitness/form is down to injury. It wouldnt surprise me if he is putting his hand up to play and getting needled up pre match, just so he can get on the park and help out his team mates. Knowing however that his body cant handle more than 20 minutes.
The question then is whether this is the right thing for the player and coaching staff to do. I dont think it would be, but perhaps they see even a small contribution as helping the cause.
