You will have one if not both back for finals, which is when it will matter. Playing a ruck down, or having a poor substitute for the home and away games is not going to be the difference between you making finals or not.I'm well off the pace. Naitanui out is a huge blow and not having Lycett back either (and then coming back without match fitness) puts an end to my aspirations for this season. I will get smashed in some of the early rounds.. but I suspect most teams would in any given round if you took out their two best rucks.
I also expect you to trade for a pretty good option early in the season, you are the trade ninja afterall
