Just a quick question, and I'm not being a troll, but have you been watching Brown's defence over the last two years. I know he's a bit bigger than Cullen, but I seriously cannot remember a single game that I would be able to say "great defensive effort by Lewis today, he really shored up the middle third with some solid defence" It could be just me, but my recollections are me screaming at Brown to get out of the ruck as he comes second or third man in. When he tries to defend high, far too often he Arm grabs, and he has got a stupid penalty in him. Then there is his attack and running game where he offers basically nothing (he's thrown one pass that has led to a try in two seasons.) Cullen offers much more in attack, and I feel if he's any worse than Brown in defense, it wouldn't be by much.
