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.

Jared Cook, Tennessee Titans (78 percent)

As the Titans attempted a comeback in Week 15, Cook added to his target total, an exorbitant 11, with nine catches, on the day. That was nearly a quarter of his receptions on the season. Before that look load, he was targeted just twice in the previous two contests combined.

But Cook and the Titans will go up against a depleted Jacksonville Jaguars secondary. They've faced some competent tight ends but haven't been burned by the position statistically. This defense is banged up, though, and remains a solid matchup play for any receiving option. The Titans want to keep Cook's involvement at a high level for the last two games of the season, so it's a good time to test it if you're desperate.
