Rank the Performances is exactly what it sounds like: an opportunity for readers to have their say. Click the thumbs up button to move the player up the list—or to help keep them on top of the list. Click thumbs down to knock a player closer to the bottom. You don't have to vote for every player and you're allowed to change your vote once.
It's part player of the game and part player rankings. Look for the December Player of the Month vote based on this month's Ranker polls at the start of January.
