With the regular season winding down, it's unlikely we will see any more major transactions before the beginning of the postseason.
Most of the trade conversations taking place this time of the year, if there are any at all, are just meant to gauge interest for deals that will take place later this winter. Some teams will make deals to ship their star players in the final year of their contract to other teams for a greater return.
This posting is not meant to suggest that each of these players mentioned here will be dealt this winter, but these players will likely be made available if the right deal is presented to their current employers.
We'll see how the offseason plays out and which players remain in the same uniforms. Some other players of note will likely find their names stirred up in trade rumors as well, and we'll undoubtedly speculate it right here.
Until then, though, here is the top player at each position that may be available this offseason as it currently stands with time still left to play in 2011.
