No but I think it's good enough, or else we wouldn't have the second best defence in the NRL. I'll keep coming back to this. The idea is to win games, and that requires attack and defence. I don't have a problem with our defence. Of course we're going to concede tries, and when we do it'll most likely be around our weakest defender Mitch Moses. Teams organise to generate overlaps on that side, and against an overlap the outside backs can't just "stay on your man, idiot". The outside defenders need to make a decision against superior numbers and it's up to the opposition to read that and make the correct play. If Blake and Ferguson just rigidly mark their man you'll find Moses by himself against a fullback and an edge forward. That would be a disaster a lot more often than what's currently happening.
When Sivo and Jennings scored all their tries this year did you stop and wonder why the opposition defenders let them get outside them?
