After claiming the scalp of South Africa in the autumn after a series victory in Argentina last summer, there had been high expectations for Scotland heading into the Championship.
And Kellock says it is time for Scotland to start delivering against an England team, the 29-year-old admits he has been hugely impressed by.
"We certainly are due everybody a win," he added. "There was a large degree of expectation before the Championship which was well merited based on the results we've had over the last couple of years.
“So far it's not been anywhere near where we wanted it to be or where anybody else wanted it to be.
“We need to go down, we need to perform and we need to play well. If we could do that we could get something special out of the game.
“I watched their first game against Wales and thought they were maybe not quite as good as everybody thought.
“But then they changed tactics and the last two games they've looked even better.
"There was a definite ploy when they were playing against Wales and they did it exceptionally well.
“There's a lot of areas that need to go right for us, but if they go right we've got an opportunity. We need to control the ball, we need to stop their counter-attack, we need to stop the set-piece.
“It's something we've not done in a game so far. We've done some things extremely well, but there's always been two or three areas that we need to tighten up on.
“That's what England have been very strong at. They have got everything working and going in the same direction.”
