As Cubs President Theo Epstein concluded a teleconference Thursday explaining the trade of troublemaking pitcher Carlos Zambrano to the Marlins, a reporter good-naturedly asked if there was any significance in getting, literally, a former choirboy.

Epstein quickly answered no. Then he paused.\

"I should point out, too, that you don't have to be choirboys to be accepted into the Cubs clubhouse," Epstein said. "We're not running a popularity contest. You just have to be a good teammate who is accountable and somebody who teammates can trust, put the team first, prepare hard, play hard. It's not that difficult."
