This time of year, they talk often, just to see who's being offered and who they are asking about. For instance, if Doug does not see a match with Cincy, he might call Wayne just to discuss another offer or another team...Doug might say, "You know, I hear the Dodgers might like to add a pitcher, have they called about Lohse?", and Wayne will say they did, but only wanted Harang for a prospect Doug covets. Doug could then call LA to make an offer since they are dangling that kid for a good arm. I remember one GM saying he called Theo Epstein to leave him a voice mail at 4AM and Theo answered the phone, but said he couldn't talk, he had another GM holding. Teams that want to move some players probably talk to every GM once a week 'til the end of July.
