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.

Alex D. Smith, San Francisco 49ers (99 percent)

Will 49ers' Smith strike gold this time?

The run-first Niners had enough with Shaun Hill's mediocrity and brought in Smith for his ... well, different name. His opponents' lead-protecting coverage and San Fran's chuck-fest aside, he found tight end Vernon Davis for three touchdowns and put up serviceable numbers.

His bust status aside, Smith piqued San Fran's interest; they've already named him their starter for Week 8. They have another chance to justify his original paycheck. He could cash in for bye-ridden fantasy owners against the Tennessee Titans (Week 9) and Chicago Bears (Week 10), two above-average fantasy matchups for the position. Just don't overspend.
