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.

St. Louis Rams (91 percent)

Really? Yes. They're a top-10 sacks team (2.25 per game so far) that per contest has registered one pick, recovered 1.50 fumbles and allowed an average of just 13.0 points. St. Louis is bending with ample yardage allowed, but not breaking. It seems head coach Steve Spagnuolo's influence is finally coming through in his second year at the helm in the elements of pass rushing and takeaways.

Their Week 5 tussle with the Detroit Lions should be an enticing opportunity to try the Rams. They face the San Diego Chargers next week but go against the Carolina Panthers and Tampa Bay Buccaneers thereafter. The Rams are at least worth a cycle play until their Week 9 bye. 

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.

Carolina Panthers (91 percent)

Carolina's D held the New Orleans Saints in check - relatively - in Week 4. While they're struggling with sacks (just one per game so far), the Panthers have picked off 1.25 passes and recovered 0.75 fumbles per game. If your D is on a bye and your free-agent pool is almost drained, the Panthers might help you float for this week.

The Chicago Bears are next on Carolina's docket, and they had no protection for quarterback Jay Cutler (concussion) last week. Cutler's status for Week 5 is uncertain. If Caleb Hanie or Todd Collins has to take over, that's something to take advantage of in the fantasy world. As of press time, Cutler is expected to start.

Also, Mike Martz's system usually turns the ball over a bit. Carolina's pass defense is the stronger part of their makeup, too. Carolina won't save your season, but they could at least bide you time.
