With the fantasy playoffs coming and the byes over, it's time for your waiver wire approach to change.
No longer are you stashing players for future impact. If you have a chance at the playoffs, you know your established starters. Unless injuries strike, you don't want to take a player off of waivers and slide him right into your lineup.
It's also time to clear out guys you won't ever start in favor of depth. If you are not going to use mediocre or unreliable players like Frank Gore or Michael Crabtree, cut them loose. What you need now is insurance at the all-important running back position.
