Every year free agency brings a lot of excitement to football fans. They can’t wait to see what their teams will do to improve over the off-season. For fantasy football players, it is important to know all of the free agent moves, as in some cases, a player's’ value increases, and in others it sinks like a rock. It is best you are up to speed before draft day as this could determine whether you need to bid one more dollar or if you should bother bidding at all. I have scoured the depth charts and threw together what I consider 8 significant moves (or lack of) that may have helped change a player’s value from last season.
