With the 2012 NFL free agency period still in full swing, there are plenty of teams who have improved their roster through free-agent signings. Other teams haven't been so lucky as they've seen their roster ravaged by teams signing away their former players.
Today we are going to power rank every team by the strength of their free agency moves. Just to be clear, we're only ranking these teams by the moves they've made through free agency, not by the overall talent on their teams.
So, please don't go shooting me when you see the Pittsburgh Steelers ranked really low on this list.
