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.

Tarvaris Jackson, Minnesota Vikings (94 percent)

Jackson: Favre handcuff

Jackson played fairly well after replacing Brett Favre (shoulder) in Week 13. The mobile passer racked up 187 passing yards and threw two touchdown strikes while completing 68.2 percent of his attempts. He rushed twice for 22 yards on the day. Jackson also tossed three interceptions.

If Favre, who has a sprained shoulder, cannot play in Week 14, Jackson will get the start. The old timer admitted following the game that he couldn't have thrown a pass after suffering the injury.

Jackson isn't a great option for fantasy owners entering the playoffs, but he should be acquired if you are in need of depth. Keep in mind that Favre, as always, may tough it out to keep his streak alive this weekend.
