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.

Visanthe Shiancoe, Minnesota Vikings (75 percent)

Ponder improves his value

Still looking for a bye week filler for your tight end or flex spot? Well, Shiancoe has at least become more reliable with Christian Ponder taking Vikings snaps. The passing game now boasts more downfield potential with Donovan McNabb benched.

Shiancoe has nine catches over his last two games, including four and a touchdown in an eight-target Week 7 versus the Green Bay Packers. With Kyle Rudolph still in a secondary role, Shiancoe should see a similar workload if Percy Harvin (ribs) can't go or is limited in Week 8 and beyond. Despite his mere two scores in 2011, Shiancoe has enough of a red zone presence to make a dent.

Surrounding his Week 9 vacation are positive matchups versus the Carolina Panthers in Week 8, the Pack in a Week 10 rematch, the Oakland Raiders in Week 11 and the Atlanta Falcons in Week 12.

Fantasy football free agents: Watch list

These fantasy football free agents shouldn't be on your immediate list. They may have had a big week. They may have talent but are buried on the depth chart and merely awaiting an opportunity. Still, fantasy football players must know who they are for their potential contribution in the future.

Evan Moore, Cleveland Browns (95 percent)

Listing Moore here isn't a new development, but if Benjamin Watson takes a while to recover from his Week 7 concussion, Moore might be in for the playing-time upgrade Pat Shurmur has been promising for most of the season. Moore caught four of the five looks he earned in Week 7 Watson is a three-down TE when healthy; Moore might not play that much, but any bump in chances to add to his red zone promise should add a modicum of interest for deep-league, bye-replacement scroungers.
