Ireland's back division are yet to fire at the World Cup so far, with the forwards providing the platform for the memorable win over Australia.
But Earls insists things are about to change for the Pool C encounter with the Russians.
"It's fair to say we haven't seen the best of us and that's down to conditions and playing the right territory on the pitch," he said.
"Against America the weather wasn't great and it wasn't a day for flashing the ball around, so we kept it quite tight.
"Even then we managed to break out a couple of times.
"Against Australia there wasn't a need to throw it around the backs because the forwards were playing so well.
"You'll see a lot more from our backline, hopefully starting from this weekend.
"If we get good weather hopefully we'll spread the ball around."
