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

Houston Texans (74 percent)

The Texans have recorded 2.00 sacks and 1.60 takeaways per outing in five games since Week 7. Houston hasn't given good results for leagues that penalize for points allowed; they've allowed at least 20 points in each of their last four games. Positives: They've had some improvements against the run and have improved their front four with a revamped defensive line rotation.

Luckily, since Week 7, the Seattle Seahawks provide a haven for quarterback takedowns, having allowed Matt Hasselbeck to be sacked 2.67 times per game, and they have committed 1.67 giveaways per outing. Their aging signal caller has been sacked in each of his games since Week 1. Houston took advantage of a solid matchup this past week despite losing, recording four sacks and recovering a fumble against the Jacksonville Jaguars.
