The end of November is an interesting time in Major League Baseball, as it's a time when rumors begin to simmer heading into the winter meetings in two weeks.
There will also be an overabundance of rumors that are either false or useless. Hearing that teams are "willing to listen" on a random player says nothing because a general manager will take a phone call about any player, even if there's no intention of moving that player.
Sometimes, though, rumors come out that have merit or are at least worth discussing because it could be a sign of discontent with the player or team, or a franchise wants to move in a different direction and holds up a "For Sale" sign.
