If we can physically match manly's massive pack without a proper bench, I can't see the dragons pack named as being something we should be scared about. I'd rather face a middle rotation of Sele, Molo, Lawrie and BMM rather than Piseka, Sipley, etc that we had to deal with last week. Sua is dangerous but nothing compared to what Olakuatu posed last week which we nullified quite well.
Really there are only three things that I can see the dragons have going for them in this game is i) our thin bench, ii) the fatigue facror from playing 90 minutes last week and iii) the home ground advantage. But even i) is not a huge advantage in their favour: I don't rate their bench forwards: lawrie especially often get monstered at the advantage line and hardly makes any post-contact metres. There's a reason he can't crack a dragons side that is really struggling atm. As for ii) dragons have an even short turnaround than us, so if anything they may be a little more rustier than us. As for iii), our last game at WIN ended up a flogging in our favour. We no longer fear going to aussie to play.
I suspect this game will be like the bunnies game. It'll be a grind for the first 20-30 minutes before we pull away as cracks open through the middle. They were made to look much better than they actually are last week due to a shit tigers team. But even they were able to embarrass the dragons through the middle a couple of times. As their rd 3 game vs cowboys showed, they can fall in a heap very quickly when momentum turns against them.
