He isn't going anywhere, as when Grundy is back he will improve the side even more, maybe in a alternating role, and finding himself forward more...
I think that might be the shift. Grundy was doing 85% of the ruck role whereas once back it might be 60/40 or 70/30 and Brodes can probably look to develop some forward craft. He did kick 2 early drifting forward one day against WCE if I remember correctly.
