As a hazy shade of winter begins to cover the country, the general manager meetings are underway and the rumor mill has once again begun churning.
The Hot Stove League is upon us.
While adding pieces through free agency is the easiest way for a team to make improvements, financial constraints often dictate what signings a general manager can make.
Those constraints aren't quite as prevalent when it comes to making trades, as teams have an opportunity to perhaps shed salary from their payrolls while making improvements for the 2013 season and beyond.
Of course, in order to get something of value, something of value must be offered in return.
It would be easy to sit here and write that each team's best player or top prospect was their most coveted trade chip, but the Tigers aren't trading Miguel Cabrera and the Royals aren't trading Wil Myers.
So I'm not going to go down that path.
For a player to be included on this list, there needs to have been either a rumor from a legitimate source as to their availability or, in some cases, rumors about other players on their team not being available, leading us to believe that the player in question could, in fact, be had if the price was right.
Let's take a look at the most coveted player on each team who is potentially available via trade, and who tops the shopping lists of the majority of general managers around the sport.
