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.

Ready to trust Walsh?

Lawrence Tynes, New York Giants (61 percent)

Tynes has surpassed 100 points in a season only once in the last three years, and he finished with fewer than 20 made field goals the past two seasons. That being said, Tynes is off to a fantastic start, successfully converting all 10 of his field goal attempts in 2012. With 33 points over the last two games and a powerful offense supporting him, Tynes is a quality addition.

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.

Blair Walsh, Minnesota Vikings (78 percent)

Fantasy owners seem to have warmed to Ravens rookie Justin Tucker, whereas Walsh remains available in far too many leagues. He has yet to miss in his NFL career, and he's averaging a respectable 9.3 points per game thus far. The rookie also draws a nice matchup in Week 4 against a Detroit Lions squad that has ceded 34 points (11.3 per contest) to opposing kickers this season.

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 - Josh Scobee, Jacksonville Jaguars (93 percent)

Scobee's 20 points may rank near the bottom of NFL kickers this year, but if you throw out the team's miserable Week 2 showing he's actually averaged 9.5 per contest. On the other side of the ledger, the Bengals have given up 10.00 points per game to opposing kickers; that's tied for fifth-most and includes a league-leading 12 extra points.
