Off Kilter

There was a 25 minute rain delay tonight in the Cardinals/Pirates game at PNC Park in Pittsburgh. It was strange but for the first few innings after the delay it seemed that everyone on the Redbirds TV crew was off kilter. It was like everyone was trying to get on the same page but it wasn't happening. There is a very uncomfortable feeling in the TV truck when this happens. The Producer or the Director can't admonish the crew because we were as off kilter as they were. It took a few innings but we all got on the same page and the telecast, once again, flowed nicely like it was before the rain delay. What does the term "off kilter" mean and who came up with it? I need to know.
