Edinburgh face Ulster on the road next and Moffat has delayed naming his team in a bid to see which players impress on the training pitch.
"I'm doing things a bit differently this week - we thought we would see who is a bit sharper and who's not quite there," said Moffat.
"We didn't perform like we can last weekend and that includes everyone - from the players to the management - it was a very average performance.
"I'm a firm believer that if we perform how we can then we will win the game - all of our players feel like that.
"It's going to be physical at Ulster but we've won at their place and we know mentally we can do it."
