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.

Christian PonderPonder continues to improve with each start.

Christian Ponder, Minnesota Vikings (79 percent)
A week ago we pondered Ponder's fantasy viability; now we're championing it on the heels of another strong showing, this time against the vaunted San Francisco 49ers defense. The second-year pro was smart and decisive and showed deft touch in accounting for three scores (two passing, one rushing) in Minnesota's upset win.

Ponder is mostly making safe throws, but it's hard to imagine a win like that won't instill even more confidence in his ability to make plays.

Mikel Leshoure, Detroit Lions (12 percent)
We said a week ago that LeShoure was returning from suspension and should be owned in all formats. Well, after LeShoure's debut resulted in 26 carries, 100 yards and a touchdown and tacking on 34 yards on four receptions (while former starter Kevin Smith was a complete non-factor) we're echoing that sentiment. If he has somehow remained on the waiver wire in your league add him immediately.

Brian Hartline, Miami Dolphins (61 percent)
Even though Hartline's production nosedived from nine catches and 111 yards in Week 2 down to one catch for 41 yards on Sunday, the Ohio State product was still targeted nine times by Ryan Tannehill. Statistical fluctuations are to be expected with a rookie under center. However, that doesn't mean Hartline isn't a viable starter when facing advantageous matchups.

Atlanta Falcons (36 percent)
One week after forcing Denver Broncos quarterback Peyton Manning into three interceptions, the Falcons harassed the San Diego Chargers into turning the ball over four times in Week 3. That gives Atlanta 11 takeaways on the year, which helps make up for an average pass rush (seven sacks). The Falcons are rolling right now, and in Week 4 they welcome the Carolina Panthers, who are fresh off a five-turnover performance this past Thursday. Unless you own an elite defense the Falcons are worth adding.

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.

Tashard Choice, Buffalo Bills (98 percent)
He may not have been head coach Chan Gailey's first choice ... or even his second one ... but Choice is the last back standing in Buffalo after C.J. Spiller (shoulder) joined Fred Jackson (knee) on the shelf. Pressed into action, Choice responded with a 20-carry, 91-yard performance to help the Bills snap an eight-game road losing streak.

Choice's value depends on Jackson's status. Out since Week 1, Jackson has been targeting a Week 4 return. If he's back, Choice's role figures to be minimal. If he's out, Choice becomes someone worth owning. And Spiller is expected to miss only a week or two.

Brandon Myers, Oakland Raiders (79 percent)
Now, I'm not exactly what you'd call a "scientist," (please make the air quotes when reading) but I have concocted a theory that Oakland's tight end does in fact have his own gravitational pull. Skeptical? Well, how else do you explain 15 targeted passes and 15 receptions through three games? You can't, that's how. So, if you're stuck with an underperforming player at the position consider a stay on Planet Myers.
