I think our injuries have hurt a lot. People have stepped up to AFL level which meant we've had VFL players back-filling them.
Otherwise it's a player like Balta, who is important for structural reasons, and difficult to replace.
I think we had Conca last weekend in our team, who was only ever going to play a half. I think Houli may have done the same the week before (might have the wrong player). It catches up eventually.
