Blockbuster deals are becoming more common, and a number of big-name players have changed teams. The Adrian Gonzalez trade is just one recent blockbluster.
There could be a lot more deals that happen this winter. Teams have players with big salaries that they want to get rid of or potential stars that are currently block. In this second instance, they can either trade the prospect or the player that is blocking them.
It seems likely that at least one All-Star gets traded this winter, and there is a possibility that two are dealt for each other during the 2013 MLB offseason. Each the teams on this list have the potential to pull off a blockbuster deal, but some will be buyers and others will be sellers.
