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.

Detroit Lions (52 percent)

Suh me: Detroit rocks QBs

Averaging 3.33 sacks per game since Week 5 and 4.00 per in their last two isn't enough to give Detroit more fantasy love? What about upcoming matchups against the 0-7 Buffalo Bills and the Tony Romo-less Dallas Cowboys, along with their Week 13 dance with the Mike Martz-fueled Chicago Bears? Even if your league penalizes for points and yardage allowed, chances for sacks and takeaways await.

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.

Cleveland Browns (86 percent)

Speaking of negative franchise stigmas, the Browns have picked off 2.00 passes and recorded 1.33 sacks per game in the last four weeks. Their last two - versus the New Orleans Saints and New England Patriots, no less - have bumped up those averages to 2.50 and 2.00, respectively. Their run D has been a true Dawg Pound, allowing only 82.3 ground yards per game since Week 5. Cleveland's secondary held its ground against those two pass-happy offenses, with their yielded stats bloated by their opponents' comeback attempts.

Fine. You need more convincing. Even after their risky fantasy matchup this week with the New York Jets, they'll see the Jacksonville Jaguars, Carolina Panthers, Miami Dolphins and Buffalo Bills.

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.

NEW - Tampa Bay Buccaneers (51 percent)

Tampa Bay's run D has cannonball holes in it, and they've only recorded 0.50 sacks per game in their last four, but they've proven to be useful elsewhere at times this season. They've averaged 1.25 picks per game in the last month, and face a Carolina Panthers offense that'll have Jimmy Clausen taking snaps and likely be without both DeAngelo Williams (foot) and Jonathan Stewart (concussion).

Even when their signals were called by Matt Moore (shoulder), now on Injured Reserve, Carolina was helpful to opposing defenses: 2.67 sacks, 1.67 interceptions and 1.33 lost fumbles per game in the last month.
