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.

Shaun Hill, Detroit Lions (48 percent)

Making a case for a start

Why are you hesitating? The Lions are a top-10 passing offense this year - most of that has come with Hill taking snaps. Hill has 97 pass attempts and an average of 306.0 aerial yards over the last two games, his second tour in replacing Matthew Stafford (shoulder). Detroit has ample receiving weapons, often has to play from behind and has a nonexistent run game with a hobbled Jahvid Best (toe).

Detroit's fantasy playoff schedule is mediocre for Hill: Green Bay Packers, Tampa Bay Buccaneers and Miami Dolphins (the best matchup). In Week 12, though, Detroit plays the New England Patriots, who've allowed 313.0 yards and 2.00 touchdowns per game through the air since Week 7. The Minnesota Vikings, Cleveland Browns, Pittsburgh Steelers and Indianapolis Colts did that damage. For the season, Detroit's throwing ranks ahead of all of those except for the Colts.

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 - Sam Bradford, St. Louis Rams (40 percent)

Bradford took advantage of his matchup in Week 11 (27-for-42, 233 yards and two touchdowns) and has thrown for two scores in three of his last four games while being picked off only once. This week, the Rams take on the Denver Broncos, whose secondary is banged up and ripe for opposing passing attacks.

In their last three games, the Broncos kept the San Francisco 49ers' aerial game in check but allowed the Kansas City Chiefs and San Diego Chargers to bombard them. Denver has yielded 299.3 yards and 3.00 touchdown throws per game to this position since Week 7. KC had to throw often to catch up, so that inflated the numbers, but even if Robert Ayers (foot) returns this week, Denver's pass rush hasn't been enough to scare opposing quarterbacks.
