Word is he was exactly the same in Premier League at the Warriors. Capable of anything, but an absolute turnstyle in defence. It's not so much missing tackles I've noticed with him, it's the fact he plays a perfect soccer interpretation of the "Free role", but in defence. He is caught out time and time again. In the Souths game, he'd already come way too far in for a try to Nigel Vagana, and then the next set, he comes racing in, fortunately Smith drops it because at the point of him dropping it Cooper had come so far up and in he was 2 metres in front of the defensive line and INSIDE his centre. That's not defending as a team. He looks to me to be the sort of bloke you'd love to have chasing down a team provided you accepted you had a big chance of losing it all too, but the bloke you wouldn't want on the field if you were up by 4 with 2 minutes to play, he looks to be me the sort of player who unknowingly could blow the game for you badly.
