Novak says he's "always been a big believer" in "Eastbound and Down" actor Danny McBride but doesn't know if the show will be able to get him.
"Eastbound and Down" is in its second season on HBO.
Novak also feels the show can go on without a replacement for Carell.
He says that "the greatest accomplishment we could have, the biggest success story we could have if Steve were to leave 'The Office' and we were as good as ever."
Novak plays Ryan Howard on the show. Credited with writing 12 episodes, he has been with the show for its entire run. "The Office" is in its seventh season.
