The 2012 NFL free agency class had no shortage of superstars. Players like Peyton Manning and Mario Williams left the comfort of franchises that drafted them in favor of new surroundings and giant paydays.
Some, like Cortland Finnegan, have exceeded expectations while others have left teams shaking their heads as to how they spent millions on an underachiever (here's looking at you, Matt Flynn.)
So, let's go back to school and hand out report card grades for the ten biggest free agent signings of the past offseason.
Side Notes: Only free agents that changed teams are included in this list, and if you are looking for letter grades of "F" you are out of luck, real teachers use "E" and so will these report cards.
