He played an extended spell of 35 mins around half time. He also came on for the last 5-10 mins so the coach was probably trying to give him an extended run to improve his conditioning.
He came up with some big tackles (the Rovers fans seemed to enjoy them), the issue he had was that all the Papuans are very short. He had to bend quite far down to hit them legally.
He made some big metres in the tackle but I do feel he could have run harder to try and break through. However as someone else has already said he came on when the game was won, so not much motivation to bust a gut.
Sia was immense, he was everywhere in defence and did some great running.
