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.

Dennis Pitta, Baltimore Ravens (37 percent)

Scheffler a busy man

If there's been a silver lining in Baltimore's recent slide (at least for fantasy owners) it has to be the re-emergence of Pitta. In the last four games, Pitta has averaged 4.75 receptions, 58 yards and a touchdown. That's good production to find on the waiver wire.

Fantasy football free agents: Look to acquire

The following players will have greater significance in deep fantasy football leagues. In shallow fantasy football leagues, they are not as high of a priority but should be considered based on your fantasy football team's needs.

Tony Scheffler, Denver Broncos (83 percent)

With lots of injuries and a largely impotent running game, Scheffler has now been targeted 38 times in the past five weeks. It's still not translating into big-time production, but if you're in the market for a desperation play, you could do worse.

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 straits. Some have, however, shown some life and should be followed in case they materialize as options beyond their temporary use.

NEW - Jeff Cumberland, New York Jets (98 percent)

With the Jets' season effectively over there's no reason to rush Dustin Keller (ankle) back from an ankle injury. That's good news for Cumberland, who had one of the few productive days by a Jet in Week 15; he posted a 4-53-1 line. As has often been pointed out, young quarterbacks tend to lean on tight ends so Cumberland could a favorite of Greg McElroy.

Also helping is the apathy of the San Diego Chargers, who appear to have checked out on the 2012 season. Their work against tight ends - 5.5 catches, 56 yards, 0.5 touchdowns per game since Week 12 - isn't terrible, but the combination of factors gives Cumberland some appeal.
