Being in Sydney, I hardly hear much about Bronco players, I did hear something about Lockyer joking and thinking his funny all the time off the field? I think Tallis said that once...
From what I've seen from the media and on the field, I'd say Civo.
It was just in an article, Preston played the whole 2nd half with a broken jaw, Doc told him to go off but he refused and didn't tell teammates or coach about him.
