"We haven't made a ton of progress," Epstein said.
Both the Cubs and Red Sox are searching for managers and will be interviewing some of the same people.
"It's the responsibility for us to get the right person for the Cubs and for [Red Sox GM] Ben [Cherington] to get the right person for the Red Sox," Epstein said. "I'm not sure that will be the same person. Different markets, the organizations are in different places now, different personnel, different front offices."
