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: 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.

Brent Celek, Philadelphia Eagles (48 percent)

Don't sell out for Celek yet

It's easy to have a knee-jerk reaction to a ghost that resurrected. In Week 12, Celek caught three passes for 50 yards, including a touchdown grab, and saw bad throws on two other plays that could've led to a score. His seven targets were the most he has seen in a game since Week 6.

Michael Vick still isn't in love with using Celek, but this at least shows Celek can be useful if needed. If you own Antonio Gates (foot) or are still trying to fill in for an injured or inconsistent option, Celek could at least be worth a shot in deeps.

NEW - Jared Cook, Tennessee Titans (99 percent)

Need a deep-league tight end gamble? Cook saw 10 targets and caught four passes for 40 yards last week with Bo Scaife (undisclosed) and Craig Stevens (knee) sidelined. Rookie Rusty Smith taking snaps probably helped Cook - at least it helped someone - but Cook is talented enough to contribute on a regular basis if given a chance.

You'll be able to wait on the injury statuses of Scaife and Stevens before moving on Cook; he isn't in demand. He has a decent matchup with the Jacksonville Jaguars this week, so he could be a last-ditch play if time opens up for him. Even if Kerry Collins (calf) returns and supplants Smith, at least the offense will be opened up more in general.
