From Dave Cameron at FoxSports.com on March 5, 2015:
When it comes to trading, almost every team plays favorites. Perhaps a former co-worker is now running another club, making conversations easy and player valuations similar. Or perhaps two GMs just happen to get along well, and when one needs to make a minor deal to round out his roster, he’s comfortable asking his friend for help before polling the rest of the league. There are plenty of reasons why some organizations just fit as better trade partners than others.
This goes the other direction as well. Many teams are hesitant to make trades with their division rivals, not wanting the player they gave up on to come back and haunt them for 19 games per season, or in the case of trading a young prospect, for years into the future. Shipping a player across the country, or even to the other league, minimizes the chances that your home town fans will be regularly reminded that not every trade works out in your favor.
