There's definitely some value plays, NicNat is basically sideways but can score at the level required to outdo Grundy even when he returns.
Darcy has been really good this year. Both those options are durability train-wrecks though.
ROB probably the value play with the huge score and no Grundy this week, same bye keeps plans in place and the 180k is an entire upgrade elsewhere.
The real question is how long is Grundy out for, neck injury in a team with nothing to play for, seeing a specialist and already confirmed out for at least 2 weeks is the kind of situation that you could definitely take on and come out looking a hero if that injury drifts out to 5 weeks or ends up claiming the season. Thinking of a guy like Cunnington last year who ended up missing the season with his back or a Heppell type where they just shut them down in the end and start priming for the next season.
Hopefully we get a bit more clarity this week!
