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.

Stephen McGee, Dallas Cowboys (100 percent)

Dan your man against JAX

This depends on the condition of Tony Romo (hand). If he can't go, McGee will get a chance to build on his Week 16 performance versus the improving (and trying) Philadelphia Eagles, especially since it doesn't look like Dallas will ink another QB. His 11-for-27, 127-yard, one-touchdown performance came in a meaningless game for Dallas; he would've probably entered at some point even if Romo hadn't been hurt.

The New York Giants have had trouble defending the pass: 283.3 aerial yards, 2.50 touchdown tosses yielded to QBs since Week 12. Those allowances came chiefly from big games by Romo and Aaron Rodgers, as well as a 59-attempt Week 16 from Mark Sanchez, but McGee could see a bit more success against this more vulnerable secondary, even if he plays game manager most of the time.

Dan Orlovsky, Indianapolis Colts (96 percent)

Indy isn't fighting for a playoff spot, but they're in front for landing the No. 1 pick in the 2012 draft. Either way, Orlovsky has brought some competence back to Indy's aerial game, including a 244-yard performance in Week 16. He has lifted the games of Reggie Wayne and Pierre Garcon and boasts fantasy utility in the right setting.

Consider his game against the Jacksonville Jaguars an appropriate time to use him. The reeling Jags have allowed 277.0 passing yards and 1.75 touchdowns through the air per contest over the last four weeks.
