it is a concern this position, but I honestly don't think Wood is the answer.
I don't know if Anthony Tupou is coming back for a second season, but given the concerns over his fitness, I would be surprised if he didn't.
If he doesn't return, then there will be a quota spot available and some cap space. It may be worth broadening our horizons when looking for a replacement, and if we are still looking to bring in an extra prop, why not go for an English prop and try to bring in Cox or Mullally.
Failing that continue looking for an NRL prop, but at the same time, try to lure Brad Dwyer. I do remember reading somewhere where he wasn't very happy
Who knows this could be the position which JK can unearth a gem from the championship.
I have no doubts on Moules abilities, but don't think he is ready to play week in week out just yet
