It's our job at FFN to monitor the rankings of players from across multiple expert websites and to report back on our findings. This allows us to look at not just the rankings but the movement within those rankings. The players listed below have seen movement over the past 30 days. This doesn't mean that you should rush out, reach, and draft these guys. There's is always context around the movements. There could be multiple reasons for the inclusion or exclusion of a particular player - for example, a free agent may have recently been signed and would likely show a lot of movement relative to other players who are more established.
The movers and shakers below are the players that have seen the most fluctuation in the FFN rankings for the given time period.
