Most free-agency talk regarding the Washington Nationals this winter will start and end with their search for a second baseman. But MLB's offseason isn't called the "Hot Stove" because of aging middle infielders moving teams. 

There are several teams on the cusp of falling out of playoff contention, which is always fun as it opens up the potential for even more trade rumors.

Seven teams—the Houston Astros, Milwaukee Brewers, Chicago Cubs, Miami Marlins, New York Mets, Minnesota Twins and Chicago White Sox—are currently more than 10 games back of a playoff spot, a very tough spot from which to bounce back. More could join them soon in the land of non-contenders.
