I think what you are saying is that playing footy every week in senior football tests a player’s durability. Doorey is getting found out, but he has age on his side.
Murchie finds himself in the middle only when there are better options on the edge. Swings and round abouts finds Mataele now learning the prop game in Flegg and Murchie back on the edge. He’s under the pump however, cos the young bulls like Guymer, Brazel, Lenaz, Blackburn, Pryke, Topou and Parker and all starring him down. The only thing that Murchie has on his side is age, which shoukd give him durability.
