Out- Spencer, Bate, Strauss,
In- Martin, Sylvia, Bartram (if fit),
Stef Martin is much much better than Spencer, I don't care how he played against West Coast.
Bate NEEDS to be dropped after that game, and Sylvia picks himself as a replacement.
Strauss will be OK eventually, but Bartram is already OK, and much more intense, which we need.
Apart from that, you're struggling to make too many more changes for lack of options. Eg., I'd love to drop Miller too, but for who? Newton?
