While the NFL draft seems to become a bigger and bigger spectacle each year, the league has a long history of undrafted players making a name for themselves. Of course, very few undrafted players will become the next Kurt Warner or Antonio Gates, but that doesn't mean they can't help your fantasy football teams.
Even the most successful undrafted free agents (UDFA) don't usually see success in year one. The players below, however, just might make some noise as rookies.
Preston Williams, WR, MIA
The Colorado State product comes into the league following other recent CSU wide receivers Rashard Higgins and Michael Gallup. A 91st-percentile dominator rating athlete, Williams finished the pre-season with five receptions and a team-leading 104 yards. With ideal NFL size, the 6'4", 211-pound Williams has a chance to be a featured part of this Miami offense as the year goes on.
There is little ahead of Williams on the Dolphins' wide receiver depth chart. The only teammate offering similar size at the position is the perpetual disappointment DeVante Parker. Jakeem Grant, and Albert Wilson are both undersized, and Wilson has a significant injury history too. Veteran Allen Hurns is also coming off of a substantial injury himself and has never played 16 games.
Most importantly, the Dolphins are projected for a worst-in-the-league four wins this season. They will be trailing early and often, and that likely leads to tons of garbage time production for everyone in the passing game.
