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.

Indianapolis Colts (51 percent)

This unit was probably overvalued anyway based on name recognition, but they've done OK so far with 2.33 sacks per game (among the 10 best averages) and 1.00 picks per contest.

With byes in effect starting this week, Indy faces the Jacksonville Jaguars. Though these two squads typically play close games, the Jags should feed some defensive stats to the Colts. Jacksonville per game has yielded 3.00 sacks (one of the five highest averages) and tossed 1.67 interceptions.

The Colts could be a lineup option beyond this week, too. They face two typically sack-prone teams - the Kansas City Chiefs and Washington Redskins - that have faced sack-empty defenses for the most part. 

Seattle Seahawks (92 percent)

Any defense coming off a five-takeaway, four-sack performance with two return TDs will earn a few fantasy looks. Was the Seahawks' statistical smashing of the San Diego Chargers fluky? Maybe, because of the three recovered fumbles, their battered pass D and the Bolts' porous kickoff coverage. But Seattle has allowed the fifth fewest rushing yards per game so far, they've brought down the QB 2.33 times per contest in the first three games, and Leon Washington looks like he's healthy enough to break big returns each week.

In Week 4, Seattle faces the St. Louis Rams, led by rookie quarterback Sam Bradford and with hobbled running back Steven Jackson (groin), who have allowed 2.00 sacks and thrown 1.67 interceptions per game so far.

Warning: The Seahawks have a Week 5 bye, so that limits their immediate roster contribution. In the three weeks following that, though, they face the Chicago Bears (for leagues with decreased importance on yardage and points allowed), Arizona Cardinals (also in Week 10) and the Oakland Raiders. Those riding a defensive team carousel shouldn't ignore Seattle.
