Ruddy, 24, told BBC Radio Norfolk: "I don't think you can take anything away from us, no matter what happens at the end of the season.
"To come into this league against some very good sides, to be second at this stage is remarkable really."
City's 1-1 draw at Middlesbrough on Tuesday means Paul Lambert's side have lost just once in their last 11 games.
"It's a credit to the management, coaching staff and players, we work for each other and we all want to be in the same position and that's in the Premiership," added Ruddy.
"If we keep playing as we are and keep picking up points, who knows, but we're content with playing every game as it comes."
I think Ruddy has been great, some of the saves he has made are class, he is now commanding the box better and is always looking to get the ball out quickly

Ruddy, who arrived at Carrow Road from Everton in the summer, enjoyed an impressive outing against Boro, frustrating the Teesiders with a string of saves.
The former Cambridge United goalkeeper displayed indifferent form early in the campaign but believes he is starting to show his true ability, despite injuries forcing regular change in City's defensive line-up.
"I was a bit shaky to start with but I think I've settled in nicely," Ruddy said.
"It's never easy when your centre-halves keep changing all the time, but with the quality we've got in that position you never worry.
"We've stopped the flow of goals we were conceding a few earlier in the season, but we're looking solid."
