I’d rest the captain and grimes.
No point testing those hammy’s with a trip to SA against the wooden spooner.
That allows Astbury to come back, I’d also leave Markov in - while the back 6 is settled I’m a little worried Bachar is still is little below his best and Markov gives us good running support across the back 50.
I reckon that Caddy is the perfect replacement for Lynch, he’s a nice mark and a lovely kick for goal and can give Jack the chop out he’ll need as the sole key forward. Chol can also pinch hit in the f50z
So, for me:-
Ins
Astbury, Shedda, Chol, Caddy
Outs
Cotchin, Grimes (both rested), Soldo, Lynch
