Can someone please explain to me why Mathews is still in the side?

But is Lockyer Collingwood's most damaging player?

its subjective, but along side Dane Swan, I believe he has been one of Collingwood's best in the midfield.

What was with the stripe across the top of his head?

I'll say it again. Matthews is a workhorse.
His job is to defend. He does his job admirably.
