The time has come for fantasy owners to drop certain underperforming players or players who have seen their roles change drastically. With eight weeks of data, fantasy owners have a large enough sample size to make informed decisions about which rostered players belong on the waiver wire.
The difference between winning a championship or not could be as small as deciding to drop a player that you thought was a sleeper but turned out to be a bust. It's been proven that the most dominant fantasy owners understand the importance of foresight. Sometimes, you have to move on, just as NFL teams move on from players throughout the season.
