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.

Brandon LaFell, Carolina Panthers (25 percent)
With Carolina's running game clicking, quarterback Cam Newton only attempted 20 passes in Week 2. Eight of those were aimed at LaFell (double that of Steve Smith), which he neatly turned into six receptions and 90 yards. He appears to be solidifying his status as the team's No. 2 receiving option, which should at least make him valuable receiver depth.

Dennis Pitta, Baltimore Ravens (63 percent)
We said last week to keep an eye on Pitta. Now, after another week in which his production (eight receptions for 65 yards on 15 targets) dwarfed that of Ed Dickson (1-23, 4), we're saying it's time to pounce. The third-year pro is emerging as quarterback Joe Flacco's go-to guy, at least on the short and intermediate routes.

Right now Pitta is more of a volume receiver, which makes him ideal in point-per-reception formats. Still, at this juncture failing to act would be ... wait for it ... "Pitta-ful."

Justin Tucker, Baltimore Ravens (68 percent)
After going 3-for-3 on field goals as part of a 15-point NFL debut, Tucker showed it was no fluke by nailing all three of his field goal attempts again in Week 2, including kicks of 51 and 56 yards. Baltimore's offense has been stalling under quarterback Joe Flacco, which is good news for the rookie kicker. With 26 points and five field goals of at least 40 yards already under his belt, Tucker is worth adding immediately.

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.

Sam BradfordICONBradford warrants consideration as a QB2.

Sam Bradford, St. Louis Rams (56 percent)
Bradford was dismal in 2011; thus, it's understandable if he wasn't in your 2012 draft plans. After looking efficient in Week 1, however, Bradford looked like a legitimate playmaker against the Washington Redskins. His 310 passing yards were his most since October of last season, and his three touchdown passes matched a career high.

Tougher matchups are looming for Bradford, beginning this coming Sunday against the Chicago Bears, but he has shown enough to warrant consideration as your backup signal caller.

Andre Brown, New York Giants (100 percent)
When starter Ahmed Bradshaw (neck) exited, the G-Men turned the ground game over to Brown and not first-round pick David Wilson. Brown responded with 90 total yards (71 rushing) and a touchdown, helping to rally the team past the Tampa Bay Buccaneers. Bradshaw is set to undergo an MRI on Monday, which should shed some light on the severity of his injury.

Wilson might work his way back up the depth chart, but his chances of doing so in the immediate future don't look bright. Clearly, if Bradshaw is expected to miss extended time Brown immediately becomes a priority addition.

Arizona Cardinals (76 percent)
It was easy to overlook Arizona's solid Week 1 showing (two turnovers, three sacks, 13 points allowed) since they were hosting a rookie quarterback. That task became exponentially more difficult this week when they traveled across the country and largely shut down the New England Patriots.

The Cardinals harassed quarterback Tom Brady, sacking him four times and holding their explosive offense to 18 points.

Arizona's relentless pressure hasn't resulted in a ton of big plays yet, but that could all change this coming Sunday when they host turnover-prone quarterback Michael Vick and the Philadelphia Eagles.
