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.

Russell Wilson, Seattle Seahawks (53 percent)

We've been championing Wilson in this space for a while now, and the rookie just continues to impress. He matched his career high with 293 passing yards in an overtime win against the Chicago Bears in Week 13 and threw for two scores - that gives him nine touchdowns and zero interceptions in his last four games. He also established a new high-water mark in rushing yards (71) for the third consecutive week.

An emerging dual threat, Wilson has become a legitimate weekly starting option and should be owned in all formats.

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 - Nick Foles, Philadelphia Eagles (83 percent)

Given how well Foles played in the team's Sunday night loss, it came as no surprise that head coach Andy Reid will go with the rookie for the rest of the season. This week Foles faces the Tampa Bay Buccaneers, who have been a sieve against the pass all season long. In the last month they have given up 296 passing yards and two touchdowns per game. It's always a risk to go with a relatively unproven commodity at playoff time, but Foles' performance, combined with his matchup, give him some legitimate potential.
