Chaplin is a very good player, anyone who doesn't have him best 22 should do the honourable thing and close their OER account so as not to waste the time of people who know the game.
Morris has a place but it should be as a small defender. I think Astbury will miss as will Vickery who I would play.
I'd also play Morris back and play Knights forward if fit with Batchelor or Lennon getting squeezed out.
I reckon it will be something like:
B: Grimes Chaplin Batchelor
HB: Houli Rance Vlastuin
C: Ellis Martin Hunt
HF: Deledio Griffiths Lennon
F: Edwards Riewoldt Morris
R: Maric Miles Cotchin
Int: Grigg, Conca, Lambert
Sub: Lloyd
