I'll be very surprised if Callum is fit that he doesn't start, as he is the captain and our leader on the park, and his experience in these games is vital.
The 2 wide players will no doubt be Maeda and Kuhn who is starting to impress me. Kyogo has to start as he is a Hun skelper and he terrifies them. The back 4 all being available, I expect will be Johnston, CCV, Scales, and Taylor.
As for Hatate, I wonder if Callum starts, it's wise to start 2 players who haven't played a great deal due to injury in a game that is likely to be physical and played at a furious pace. I'm therefore not sure Brendan will risk starting both Callum and Hatate. We shall see.
At least we now have better options to choose from...
