Fantasy Football Waiver Wire: QB | RB | WR | TE | PK | DT

If you are serious about winning your fantasy league football championship, stay on top of your fantasy football team throughout the year.

Each week during the NFL fantasy football season, KFFL brings you its Fantasy Football Waiver Wire, which breaks down players to pick up. Be aggressive when picking up fantasy football free agents. Even if you do not need a player, you can tuck him away for depth or block others from adding him to their fantasy football team.

Fantasy football free agents: Priority additions

The following players should be high on your radar and are worthy of being added immediately to your fantasy football team.

Washington Redskins (59 percent)

Low-cost, considerable upside

Another bye roster casualty last week, Washington faces the reeling Philadelphia Eagles in Week 6. That's just the beginning of what could be a productive stretch; through Week 12, they tangle with the Carolina Panthers, Buffalo Bills, San Francisco 49ers, Miami Dolphins, Dallas Cowboys and Seattle Seahawks.

Their own merits play in, though: They tied for the league lead with 15 sacks through the first four weeks of the season, and playmaking safety LaRon Landry is now healthy. Buy.

Fantasy football free agents: One-week plays

The following fantasy football pickups are for those who need injury or bye week replacements. They are not players you immediately acquire - unless your team is in dire straights. Some have, however, shown some life and should be followed in case they materialize as options beyond their temporary use.

Buffalo Bills (75 percent)

Let it ride with Buffalo, whom we also listed as a rental last week, too. They're on bye Week 7, so they're worth a ditch after they face the New York Giants in Week 6. The Bills picked off Michael Vick four times and sacked him once in Week 5, including an end-zone dance following an INT. Eli Manning is coming off a three-sack, three-INT week that also included two fumbles (one lost) against a mediocre Seattle Seahawks unit.

This could be a shootout, but once again, focus on scoring systems that favors takeaways and QB takedowns. The Bills don't have a dynamic pass rush but took advantage of another shaky O-line last week. Manning has been sacked at least three times in four of the Giants' five contests. Momentum is on Buffalo's side, too, which sometimes is enough if there's a slightly favorable matchup.
